In the impression of many people, hard steel plate is one of the best materials to resist bullets, because it is strong. In another impression, ceramics are generally used to make exquisite works of art. They break when they fall. They are beautiful but very fragile. Ceramics can't stand the impact of bullets anyway. However, it is surprising that the materials used in the manufacture of modern bulletproof vests are not steel plates with strong hardness, but ceramics that break at one touch. What's against common sense to use ordinary ceramics as bulletproof vests? The reasons are as follows:     Disadvantage of Steel Plate We all know that the properties of materials are relative. Although the steel plate is strong, its weight is very heavy.If a steel plate that can block bullets is made into a bulletproof vest for level iv, the weight of the two steel plates in front of and behind the bulletproof vest will seriously limit the soldiers' ability to move in action.Do you think you can concentrate on fighting with a heavy thing? Better not take it with you!If the thickness of the steel plate is reduced to achieve the effect of weight reduction, it will not be effective in bulletproof.Not to mention the short-range design, even the long-distance design, will also make the steel bulletproof vest carried by soldiers sunken or even pierced. The soldiers were either seriously injured or killed.   The Magic Of Ceramics Can the bulletproof vest made of ceramic resist bullets? The soldiers' answer is yes, and it is the best bulletproof material since the 20th century.At least in the past, soldiers could not be avoided in the face of death. The emergence of ceramics has completely changed this situation.Why does the bulletproof vest made of ceramic have this "magic"?In fact, if only ceramics is used as material, the bulletproof performance of bulletproof vest is not as good as that of steel plate.The reason why the ceramic bulletproof vest can be bulletproof is that a special fiber with strong toughness, namely Kevlar / Twaron / Aramid bulletproof fiber, is added to the ceramics. The hardness of bulletproof clothing made of Kevlar bulletproof fiber and ceramic composite material is much higher than that of steel plate. Why do you say that?     The Reason Why Ceramics + Aramid Replaced Steel First of all, Aramid bulletproof fiber is a very dense mesh structure material.When this material is greatly impacted by the bullet, it will quickly disperse the shock wave ability of the bullet through the mesh texture, so as to achieve the effect of energy absorption.Just as the force of jumping from a high place to the ground is different from that of jumping on a mesh trampoline, trampoline will definitely be injured. Trampoline absorbs the impact force generated by the force diffusion of the human body, so that people will not be injured.Then ceramics can also play a second role, that is, to block the impact of bullets. Its bulletproof principle is the same as that of steel plate, except that ceramics and fibers can be well combined, while steel plate cannot. This is why most modern bulletproof vests use fiber + ceramic composite materials, and rarely use steel plate materials.

  A bulletproof vest is composed of plate carrier clothing and ballistic plates. What really plays the bulletproof role is the ballistic plates. The clothing is just the carrier but not bulletproof.    Ballistic plates are divided into two categories. One is soft plates (relatively weak protection ability), and the other is reinforced / composite hard plates (relatively strong protection ability).    The soft plates are usually made of high-performance fibers (such as UHMWPE and Kevlar). Its bulletproof principle is that when the bullet / fragment hits the fiber layer, the huge impact force will be consumed when stretching and shearing the fiber layer. At the same time, the fiber layer will spread the impact force generated by the bullet / fragment to the area outside the impact point, so as to absorb the impact force. The soft plates can resist the bullets of pistols and shotguns or fragments of explosives such as grenades, as well as long-distance automatic rifle attacks (not at close range). The hard plates are made of metal, ceramic, high-performance composite plate and other hard materials on the basic of soft plates. The bulletproof principle is that when the bullet hits, firstly the metal plate, ceramic plate or composite plate in the bulletproof plate contacts the bullet (equivalent to the first line of defense). At the moment of contact, the bullet and these hard bulletproof material plates may crack, which consumes most of the bullet’s energy. As the second line of defense as well as a buffer, the soft bulletproof material absorbs and diffuses the remaining energy of the bullet, so as to achieve the purpose of bulletproof. The hard plates can resist more powerful weapons, such as automatic rifles.  

Riot gear is designed to protect police officers and other law enforcement personnel from physical harm in various scenarios. Riot gear typically includes body armor, helmets, shields, and other items that protect from various types of injuries that can occur in the field. Another key use for riot gear is preemptive riot deterrence. By having law enforcement and military personnel visibly wearing riot gear in potential hotspots ahead of time, it sends a message that authorities are prepared for any potential violence and are not afraid to use less lethal force if necessary. This can help discourage would-be rioters from taking any action in the first place.   What does riot gear protect you from? Riot gear can offer different levels of protection from physical attacks, depending on the materials used, the type of attack, and various other factors. Full riot suits are effective at protecting against the tactical accessories officers use during crowd control situations, like pepper spray, tear gas, and rubber bullets. Riot gear also provides a measure of anonymity for police officers, which can help de-escalate potentially tense situations.   When was riot gear invented? Riot gear was first invented in 1921 by French police, who desired a non-lethal way to manage large or unruly crowds. Around 60 officers were initially trained in crowd control in Paris, and the movement spread worldwide. In 1925, China also began to use non-lethal forms of crowd management and brought even more innovation to the table with their invention of holsters to prevent weapon theft and shields to block projectiles. Since then, riot gear has been used by law enforcement and military personnel during riots, protests, and other public disturbances.   What is riot gear made from? Riot gear is typically made from synthetic materials that are both lightweight and durable to offer protection without added bulk. This can include Kevlar, nylon, polycarbonate, and other similar materials. Important Considerations When Using Riot Gear Riot gear needs to be comfortable to wear for long periods, since officers may be out in the field during a protest or other civil unrest situation for many hours without a break. Riot gear should also fit properly to offer the best possible protection, and should be regularly inspected for damage. Equipment should be cleaned, well-maintained, and kept in a proper storage facility when not in use. Officers should also be trained in the proper use of riot gear and how to respond to different scenarios involving civil unrest using their gear. Failure to adequately train officers before sending them out in the field can have serious consequences, both for the safety of officers and the people they are protecting.

  Ballistic PASGT Helmet is a kind of U.S. military standard individual helmet.   The history of the U.S. Army's standard steel helmets can be traced back to the First World War. At that time, the U.S. Army had no standard steel helmets, and the British "flat disc" steel helmets were urgently adopted. The English helmet remained in service until the middle of 1942 and was later replaced by the famous M1 helmet. The M1 helmet is the first-generation standard helmet developed by the United States. It has a hemispherical shape and a wavy curve at the bottom, which increases the protective area. It is quite simple and classic. The M1 helmet has experienced World War II, the Korean War, and the Vietnam War and has become the most important symbol of American soldiers.   In the early 1970s, DuPont of the United States successfully developed a new type of synthetic fiber-Kevlar, which has low density, high strength, good toughness, high temperature resistance, easy processing and molding, and its ability to absorb the kinetic energy of shrapnel is 1.6 of nylon. Times, twice that of steel, has a very high military prospects. At the same time, the US Army's Natick Research Lab (Natick Research Lab) conducted a study aimed at reducing the weight of infantry protection systems. In the Vietnam War, infantry helmets and bulletproof vests used steel materials, which were quite heavy. Nadik Laboratory hopes to use new Kevlar materials to make a new generation of lightweight helmets and bulletproof vests to reduce the load on soldiers. However, the focus of helmet research and development changed from reducing weight to providing better protection while maintaining the same weight as the M1 helmet.   After determining the manufacturability of the Kevlar-29 material, a research and development team led by Phil Durand began to conduct detailed anthropometric measurements to determine the best bulletproof shape of the new helmet, and strive to improve the bulletproof capacity/weight The ratio, increase the protective area, pay attention to the fitness of different head types and wearing comfort. Finally, the new helmet appeared with a low profile and a low center of gravity. The ear protectors were added and projected outward. The front edge was designed with a small brim. The protective area was expanded to the soldier's ear and neck position. In addition, the protruding ear protectors allowed sufficient space to install communication headsets.     The new helmet fully focuses on ergonomics and improves the comfort of the M1 helmet with a high center of gravity and long-term wearing. In addition, due to the low thermal conductivity of composite materials, it is more suitable for use in deserts and severe cold areas. At the beginning, the new helmet had three sizes (small, medium, and large) to fit most male soldiers, but in the 1980s, a large number of women entered the Army and Marine Corps. Because women had smaller average head circumferences than men, Therefore, an ultra-small size is added to the above three sizes. During the Gulf War in 1991, the U.S. military ordered an oversized helmet for General "Storm" Norman, who had an oversized head circumference and a burly figure. At that time, the Federal Penitentiary Factory urgently ordered a batch of 1,000. Since people who fit this helmet are very rare, it will not be reproduced in the future, and helmets of this size are now quite rareThe silhouette of the new Kevlar helmet is often accused of resembling a Nazi helmet, but it is by no means based on the German M35 in World War II. The Nadic staff pointed out that the shape of the M35 and the new helmet was determined by the designer based on the probability of head trauma in the battlefield, the interaction between the helmet and the equipment, and the scientific data of anthropometric measurements. There is no problem of imitation. The guys at Nadic Lab didn't like people to compare their helmets with the German M35, because in the First World War, a Slade#5 helmet designed by the United States was discarded because it was very similar to the German M16.   For comparative testing, the first batch of prototype helmets were made of glass fiber and Kevlar, and two hundred prototype helmets of each material were manufactured. The two materials have the same ballistic performance, but the glass fiber lost to Kevlar in the durability test. These helmets are easy to distinguish in appearance. Nadiq painted jungle camouflage directly on its surface. The helmets that will be officially equipped in the future are all monochrome. There are four colors of olive green, black, desert yellow, and UN blue. Soldiers can Replace the camouflage cover cloth as needed to suit the battlefield environment. These helmets are made by a small marine fiberglass modeling company called Geonautic Co., Ltd.   After the helmet was shaped, the naming battle began again. Nadik suggested calling it Duramac, because Durand and another person named McManus were the main promoters of the plan. Finally, the military called it the PASGT helmet. PASGT is the abbreviation of the Personal Armor System for Ground Troops (Personnel Armor System for Ground Troops). The armor system refers to the new Kevlar helmet and the matching Kevlar vest. The PASGT vest is also Developed by Nadic.     PASGT helmets are produced by several manufacturers in accordance with the military standard MIL-H44099A. The helmet’s design goal is not to resist the direct fire of rifle bullets, but to defend against fragmentation weapons such as grenades, landmines, mortars, bombs, and 9mm pistol bullets. Direct shot of shotgun bullets. A two-layer suspension system is installed in the helmet to keep the helmet and the head at a distance of 1.3 cm, which not only maintains good ventilation, but also effectively reduces external impact and protects the head from shock. The head protection area (medium size) is 1,129 square centimeters. The helmet can resist (V50 ballistic performance test value) the impact of fragments at a speed of 663 m/s and can withstand high temperatures of 190°C. In contrast, the V50 value of the old M1 helmet is about 300 m/s, and the protection performance of PASGT is increased by 50%. The helmet is fixed at two points, the length of the jaw strap is adjustable on both sides, and the buckle is set on the left side. In addition to the helmet cover, an elastic band called "cat's eye belt" is also put on the outside of the helmet. In addition to fixing the camouflage, the cat's eye belt is also inlaid with a fluorescent sheet on the rear side, which is convenient to follow when the column is marching at night.   After PASGT helmets began to be equipped, American soldiers gave it the nickname "Fritz". After experiencing the comfort and excellent ballistic performance of PASGT, all soldiers regarded it as the most important protection. Outfit. In the Museum of the 82nd Airborne Division, there is a PASGT that blocked the AK-47 warhead during the invasion of Grenada.   One of the main manufacturers of PASGT, Gentex (Gentex) of Carbondale, Pennsylvania, has manufactured civilian industrial safety helmets based on it, and Keydril, an international oilfield drilling contractor, purchased 1,000 of them. Of course, the protective performance of this helmet is first-class, but due to high cost, high weight and unusual appearance, further sales were restricted. As a result, Jintex discontinued the helmet after the completion of the transaction with Keydril.   Since it was put into production in the 1980s, PASGT helmets have been undergoing multiple stages of improvement to improve the comfort, stability and protection of PASGT. The recently produced version uses Kevlar KM2 fiber, which can be woven more tightly than the old Kevlar, and has a weight reduction of 10%. The V50 value is increased to 686 m/s, which further improves the ballistic performance. The PASGT helmet of the U.S. Marine Corps has been using Honeywell’s Spectra fiber material since the end of the 1990s. It has better ballistic performance than Kevlar and can be 30 lighter than Kevlar. % the above. However, this material is more difficult to mold than Kevlar. When manufacturing the helmet, it is necessary to laminate the resin matrix and the unidirectional fiber sheet to form a hard and rigid plate structure. If the manufacturer does not handle it well, the Spacotra helmet is in the wild It is easy to layer under the environment.   The suspension system has also been improved, the leather headliner has been widened, and the fixing method between the sweatband and the sideband has been improved. Detachable shock-absorbing pads were also issued for the paratroopers to provide more collision protection during parachuting. The PASGT helmet also plans to use a more comfortable three-point fixed jaw strap. In addition to the fixed points on the sides of the ears, the fixed points behind the head are also added, so that the helmet will not shake back and forth during strenuous exercise, and the helmet will be more stable. The US Army tried a three-point fixed jaw belt during peacekeeping in Haiti, but it was not promoted due to conflicts with existing equipment.   The U.S. Army also recently installed a modified PASGT deformed helmet-Modular Integral Communication Helmet (MICH), which can provide improved protection, practicality and comfort. It was issued to Special Forces in 2001. MICH has a lighter body than PASGT helmets. The brim is removed and a variety of Kevlar fibers are used for bonding. MICH uses a new seven-pad suspension system. The pad is composed of two foam materials, and the suspension system is attached to the inside of the helmet top through a series of Velcro fasteners and is fixed with a four-point jaw strap. The most important feature of MICH is that the duplex communication module can be installed under the ear protectors, which replaces the previous bulky headset system and improves the soldiers' battlefield perception and coordination capabilities. MICH has only medium and large sizes, but it can be adapted to different head shapes through different size pads. MICH is only equipped with special forces and is used in the US Army Land Warrior system. It will gradually replace PASGT as a standard helmet in the future.   Following the equipment of the US military, the revolutionary PASGT helmet has been widely adopted by other Western countries. The new generation of bulletproof helmets in China can also be said to be PASGT-style helmets. helmets are made of aramid fiber (Kevlar) developed by China. Not a straight line. In order to reduce production costs,  helmet has only one type of helmet, and the head circumference can be adjusted through the suspension system. In addition, the three-point jaw strap of the suspension system is lined with wool on the head contact area, which provides excellent comfort and stability. The protective performance of the  helmet is better than that of the first-generation PASGT helmet of the US military, and its curb weight is 1.45 kg, which is lighter than the smallest size of the US military PASGT. The helmet began to be equipped with the Hong Kong in 1997 and has gradually become our military standard helmet.     Since the development of the PASGT helmet in the 1970s, non-metal composite individual helmets have gradually become a trend. A safe, comfortable and beautiful helmet can undoubtedly greatly enhance the morale and confidence of soldiers.

Staying protected in tactical situations is very important for you and your team, choosing the best protective gear that would ensure that, is a daunting task, that requires a lot of research and understanding of the capabilities of such equipment, the materials they are made of and what gear to use at which situation. Keeping your head and brain protected from injury would take the highest priority and is critical to function and survivability, and something that is constantly being overlooked is the padding of ballistic helmets which can significantly reduce the trauma to your brain after being shot at or from shrapnel and explosives. In this article we will try and explain the best ways to choose the best options for you and your team to stay protected and to ensure your safety during and after tactical situations. There has been a great deal of innovation that has gone into the development, research and testing of protective gear materials, design, engineering, construction, and manufacturing of bulletproof helmets in recent history, after the Iraq and Afghanistan wars. NIJ testing mainly gives you an idea of what to expect of specific bulletproof helmets and how they will function against specific rounds or threats, for example a High-Cut (III-A) Tactical Bulletproof Helmet would protect you against or up to level III-A rounds, however the NIJ rating doesn’t specify anything about padding – or in that case extra-enhanced interior padding – and how it will decrease your chances of brain trauma or internal injuries if shot at by a bullet, unlike other ballistic helmets offered by other bulletproof helmets providers available on the market.     Research has shown that the padding of a bulletproof helmet can significantly reduce the chances of traumatic brain injury (TBI) from being shot at. At EDI we went to great lengths to design the best bulletproof helmets on the market that would ensure you and your teammates protection and safety when situations get tough. Not only did we use the best materials to make our helmets exteriors, but we also used the best materials for the interior padding to enhance your comfort, safety and protection and mitigate traumatic brain injury (TBI). Our great range of ballistic helmets will ensure your protection during and after tactical situations. Starting with our top of the line the High-Cut (III-A) Tactical Bulletproof Helmet, unlike other bulletproof helmet providers, our High-Cut Bulletproof Helmet is equipped with extra-enhanced interior padding that significantly helps reduce brain trauma or internal injuries if shot at by a bullet. The extra-enhanced interior padding system includes seven (7) high-density memory foam pads that allow users to comfortably wear the helmet. Unlike other ballistic helmets which only include a couple of interior padding, the seven (7) pads are comfortable, lightweight, and can also be removed for cleaning or replacement. In addition, users can remove some, or all, of the padding in case they need extra space around their head to accommodate cold-weather head gear, or head-mounted communication devices. Our enhanced padding is a huge advantage and will significantly increase your chances of survival and injury if shot – it is hard to find other helmets at our price point that have such a great and high-quality interior padding system. Our MICH (III-A) Bulletproof Helmet and our MICH (ACH) HELMET (III-A) – WITH SIDE RAILS AND FRONT MOUNT are equipped with durable pads (7 pads in total) along with a strong head harness with rubber chin up. The trauma pads on the inside are very, very comfortable. Unlike other bulletproof helmets, our bulletproof helmets are equipped with extra-enhanced interior padding that significantly helps reduce brain trauma or internal injuries if shot at by a bullet. This is a huge advantage and will significantly increase your chances of survival and injury if shot. Finally, our PASGT (III-A) Bulletproof Helmet is equipped with a durable head harness as well as a cushioned interior and headband for maximum comfort during many types of situations requiring a bulletproof and tactical helmet. Unlike other bulletproof helmets, our bulletproof helmets are equipped with extra-enhanced interior padding that significantly helps reduce brain trauma or internal injuries if shot at by a bullet. This is a huge advantage and will significantly increase your chances of survival and injury if shot.

Your head is the most important part of your body, which is why YF manufactures three ballistic helmet models to offer police and military the bullet-proof protection they need. Plus as the manufacturer, YF is able to offer helmet customizations using a variety of colors, retention systems and padding configurations. Through these customization options, we’ve been able to help police and military forces in over 70 countries around the world procure ballistic helmets that meet their exact specifications.  We’re here to help you select which helmet is right for you! Read on for YF’s guide to each helmet’s fit and recommend usage scenarios.   THE PASGT MODEL Pronounced “PAS-GIT”, the PASGT helmet is the traditional ballistic helmet model that has been protecting men and women in serving forces around the world for decades. This helmet has a small “visor” above the head, and offers good ear protection. Popular among military members, the YF’s PASGT model helmet protects up to level III-A threats. Tried and true, there’s good reason the PASGT model has been YF’s “classic” ballistic helmet for years.   THE MICH MODEL With a newer design than the PASGT model, the MICH helmet does away with the small “visor” about the head. The MICH model is compatible with side rails, a gas mask, and a front NVG mount, making it ready for tactical operations. And since the helmet dispenses with the ear protection flaps, users can easily use headphones with it.   YF’s latest ballistic helmet model, the FAST offers the user unrivaled mobility. The FAST ballistic helmet includes side rails and front NVG mount for tactical operations. Its high cut makes it particularly easy to integrate devices with these features, without compromising a user’s comfort or mobility.   Unlike the PASGT, the FAST helmet’s shape does not include ear protection flaps. This makes it possible for the user to easily use headphones to stay in communication with their team.

Many people may have such a misunderstanding that bulletproof vests can be used as long as they are not broken. In fact, this is not the case. As the service life of this equipment increases, its anti-ballistic performance will also decrease. Only by doing a good job of maintenance at ordinary times can the service life be extended to the greatest extent. Here are a few things that need to be paid attention to in the ordinary maintenance of this equipment for everyone to understand and refer to.     One is to clean the bulletproof vest regularly. The jacket of this equipment can be washed in the washing machine, but the bulletproof panel must be taken out before washing. When cleaning the bulletproof panel inside, pay attention. You need to prepare a sponge and cleaning agent in advance. The specific method is to gently wipe the level iiia bulletproof panel with a sponge dipped in the cleaning agent. Do not put the chip in the water to avoid being corroded by moisture or stains.      The second is that this equipment expecially the soft panel must not be exposed to the air long time. Exposure to the sun will accelerate the aging rate of this equipment, thereby reducing its ballistic performance and service life. When such equipment is not normally used, it must be kept in a warehouse. The environment of the warehouse must be kept at a dry and normal temperature. Do not reduce the ballistic performance because the environment is humid.     Third, if in real life, once the bulletproof vest is shot, it must be replaced in time. Although we can't see obvious changes with the naked eye, the structure of the bulletproof armor material has changed, which reduces the stability and bulletproof capacity. If it is not replaced in time, the next time it hits the same position, the bulletproof kevlar panel and the bullet-proof armor may be penetrated, thereby threatening human safety and even life.  

A riot shield is a lightweight protection device, typically deployed by police, security personnel, correctional officers and some military organizations. Riot shields are typically long enough to cover an average-sized person from the top of the head to the knees, though smaller one-handed models may also be used (round – circular – anti-riot shield). They are generally intended to be used in riot control, to protect the user from attacks and threats with blunt or edged weapons and thrown projectiles, or non-lethal weapons such as rubber bullets and water cannons. They can also be used to push back the opposing force. Riot shields have been used as an effective protection tool by the police against protestors and rioters in Europe and the UK as early as the 1960’s and the 1970’s. The British forces deployed them in the 1950’s as well.Riot shields are used in almost every country with a standardized police force (we offer customized options with languages/fonts and color). Law enforcement often use them in conjunction with a baton (check out our range of batons). Riot shields made for law enforcement are typically constructed from transparent polycarbonate (reinforced plastic) to allow the bearer to have an unobstructed view of incoming thrown objects. However, there are riot shields made from different materials (aluminum / ballistic shields) to help the bearer shield themselves from fire or other dangerous hazards like live ammunition/bullets. riot shields are effective in protecting the bearers and preventing protesters from breaking through police lines (interlocking riot shields). Common uses of the riot shields:Riot shields are typically made of transparent polycarbonate between 4–6 millimeters (0.16–0.24 in) in thickness. Shields are designed to be shatter resistant. The riot shield is designed primarily as a defensive weapon, though it can be used in an offensive manner when in direct contact with protesters. We also offer anti-laser riot shields which help the bearer from the threat of laser beams pointed at their eyes and obstructing their vision.Special event security, tactical police units, corrections officers, crisis response forces, quick reaction forces, disorder control units, and general security contracting companies all use riot shields. Outside of prison cell extractions, riot shields are almost always used for defensive purposes to protect the public in unstable situations. Their clear design gives them an unobstructed line of sight and provides immediate situation assessment.Riot shields offer protection to the user from a variety of blunt objects and projectiles. Rioters will use anything and everything nearby as a weapon in a riot or melee situation.Here’s a list of items rioters use that the riot shields can protect you and your team from:RocksGlassSmall metal fragmentsElectric shockBricksStick attacksRubber bullets

THE PROTEC-X RIOT HELMET: TRADITIONAL AND UTILITARIAN    The PROTEC-X is the traditional riot helmet. It is optimal for standard riot operations where the user’s head must be fully covered. The PROTEC-X’s full coverage offers comprehensive protection from projectiles and other threats the officer may face during a riot situation. The PROTEC-X’s visor offers full coverage for the eyes, and a tight seal around the top of the visor helps prevent liquids and gas from seeping in between the visor and the helmet shell. Because of its full-coverage protection, PROTEC-X Riot Helmet is popular for city operations where high-density protests may be expected. The PROTEC-X riot helmet is also popular with rural units, as the PROTEC-X’s comprehensive protection and utilitarian features make it ideal as a one-size-fits-all solution for unexpected protests.   For those in hot climates, a popular option is to customize PROTEC-X Riot Helmet by tinting the visor. The tinted visors thus offer sun protection in the field, in addition to insulating the wearer from tear gas and projectiles. THE TERMINATOR-X RIOT HELMET: FOR STRONGER FACE PROTECTION  This model offers ideal protection for riot situations when the officer may expect protestors to throw heavy objects at its users. The TERMINATOR-X riot helmet offers stronger face protection than the PROTEC-X Riot Helmet. With the TERMINATOR-X Riot Helmet, a heavy-duty face cage layered over the outside of the visor. This face cage shields the visor against impacts that might otherwise cause the visor to shatter. The result is that the face cage further insulates the wearer from blunt force trauma, attacks, and collisions with heavy-duty projectiles. The TERMINATOR-X’s face cage protection likewise makes it ideal during prisoner transport. Specifically, our clients have found TERMINATOR-X face cage protection especially useful during cell extraction activities. For this reason, TERMINATOR-X Riot Helmet has found a home in hundreds of prisons around the world.   A common customization requested is to add anti-fog treatment to the inside of the visor. This helps prevent the TERMINATOR-X’s visor from fogging up during operations. YF is happy to work with our clients to meet this specification upon request.    THE BUBBLE RIOT HELMET: FOR ENHANCED GAS AND SMOKE PROTECTION  Our latest Riot Helmet style, Bubble Riot Helmet is popular with police and security professionals who are exposed frequently to tear gas and other smoke elements. What makes the Bubble Riot Helmet unique is the “bubble” shape of its visor. Because the visor protrudes outwardly, this makes it easy to layer a gas mask underneath. Side view of the Mini Bubble Riot Helmet. The “Bubble” shape of the visors makes it easy and comfortable for the user to wear a gas mask beneath the visor. Because of the ability to easily layer a gas mask under the visor, Bubble Riot Helmet is most popular in urban environment riot situations where tear gas is more frequently deployed.   To help customize the Bubble Helmet further to your needs, YF offers two different options for the thickness of the Bubble Helmet’s visor. This enables your team to select the thickness of your visor based on the unique threat environment you anticipate in the field. If you wish to seek enhanced protection against heavy projectiles thrown at officers, the thicker visor will best serve your needs. If your primary concern is protecting officers from tear gas and other liquids, the thinner visor will meet your needs.
