The police body armor is composed of a jacket and a bulletproof layer. The bulletproof layer is mainly made of metal and other protective materials, which can absorb the kinetic energy of the warhead and reduce the speed of the warhead, thereby protecting the human body. So, what kind of process did the body armor go through? What are the relevant properties of the inner body armor? Let’s take a closer look at the history of bulletproof vests and related characteristics. Special bulletproof clothing Lightweight bulletproof clothing is a kind of personal protective military uniform used for protecting the human torso from projectiles or shrapnel, mostly in the shape of a vest. Bulletproof clothing made of bulletproof layer and jacket is a kind of individual protective military uniform used for protecting the human torso from projectiles or shrapnel. The thickness of the bulletproof layer is determined by the balance between protection performance and wearing comfort according to different objects. Soldiers wearing alone can significantly reduce battlefield mortality and injury rates.   Police bulletproof clothing is developed on the basis of armor. During the First World War, 80% of the total casualties on the battlefield were caused by low- and medium-velocity stray bullets or fragments, and experts were inspired by ancient armor to develop alternative bulletproof suits in the late war. In World War II, casualties caused by shrapnel still accounted for about 60%. People paid more and more attention to the development of bulletproof clothing. In the early 1940s, the United States and some Western European countries began to develop alloy steel and aluminum alloys. , Chin alloy, glass fiber reinforced plastic, ceramics, nylon and other materials bulletproof clothing, and used in the battlefield.   In the 1960s, the second generation of bulletproof clothing that replaced high-quality steel with high-quality chemical fiber materials began to appear. Since the 1970s, bulletproof clothing has undergone new developments. Body armor can be divided into three types: soft, hard and soft-hard composite. The material of the soft body armor is mainly high-performance textile fibers. These high-performance fibers are much higher than the energy absorption capacity of general materials, giving the body armor the bulletproof function. softness, called soft body armor. The protection level of soft body armor is usual NIJ IIIA AND below.

  Anti-riot armor suits are also called anti riot suits and armor suits. It is widely used in the fields of anti-riot, anti-terrorism and stability maintenance, and handling of large-scale riots.   Name: Riot Armor Suits Alias: Anti riot suits, armor suits Application scope: anti-riot, large-scale riot handling and other fields.

Ballistic helmets are widely used by military and law enforcement personnel to protect their heads from ballistic threats. These threats may come in the form of bullets or shrapnel from explosive devices. The helmet serves as a vital piece of equipment that can potentially save a soldier or police officer’s life in the event of an attack. In recent years, ballistic helmets have become more advanced, and manufacturers are producing helmets that provide greater protection while being lightweight and comfortable to wear. In this article, we’ll take a closer look at ballistic helmets, how they work, and what factors you should consider when choosing one. What is a ballistic helmet?A ballistic helmet is designed to protect the wearer's head from a variety of ballistic threats. The helmet is made of several layers of material, including Kevlar, aramid fibers, and other high-strength materials. These layers work together to absorb the impact of bullets or shrapnel, thereby reducing or eliminating the risk of head injury. A ballistic helmet may also have a protective visor or face shield for additional protection.How do ballistic helmets work? Ballistic helmets work by absorbing the energy of the impact and scattering it over a wider area. The helmet's outer shell is typically made of a hard material like a thermoplastic composite, which is resistant to penetration. Inside the shell, you'll typically find several layers of material that are designed to absorb and disperse the energy of the impact. This may include layers of Kevlar or other aramid fibers, which are woven together to provide maximum protection.When a bullet or other projectile strikes the helmet, the outer shell resists penetration while the layers of material inside the helmet absorb the energy of the impact. The impact energy is dispersed over a wider area, preventing it from concentrating on a small area and reducing the risk of injury.Factors to consider when choosing a ballistic helmetWhen choosing a ballistic helmet, there are several factors that you should consider. Here are some of the most important:Protection level: Ballistic helmets are rated based on their ability to protect against certain types of threats. You'll typically see helmets rated for protection against pistol-caliber bullets, rifle-caliber bullets, or both. The higher the protection level, the more effective the helmet will be at stopping bullets or other projectiles.Comfort: A ballistic helmet can be heavy and uncomfortable to wear, so you'll want to choose one that's as comfortable as possible. Look for helmets with padded interiors, good ventilation, and adjustable straps for a comfortable fit. Weight: The weight of a ballistic helmet is another important factor to consider. Heavier helmets may provide better protection, but they can also be more tiring to wear for extended periods. Look for helmets that strike a balance between protection and weight.Durability: A ballistic helmet should be able to withstand repeated impacts without losing its protective properties. Look for helmets with a rugged outer shell and high-quality materials inside.Cost: Finally, you'll want to consider the cost of the helmet. Ballistic helmets can be expensive, but there are options available at a range of price points. Consider your needs and budget when choosing a helmet. YF Protector is source manfuacture of bulletproof helmet including FAST MICH PASGT Model, check with us, you will have option to buy high quality helmet with reasonable price. ConclusionBallistic helmets are an essential piece of equipment for military and law enforcement personnel. These helmets provide critical protection against ballistic threats, and they're becoming more advanced all the time. When choosing a ballistic helmet, consider factors like protection level, comfort, weight, durability, and cost to find the right helmet for your needs. With the right helmet, you'll have an extra layer of protection that could potentially save your life in the event of an attack.

Many people may have a certain misunderstanding about bulletproof vest, thinking that as long as the bulletproof vest is not damaged, it can be effective for a long time. But this is not the case. Regardless of whether it is damaged or not, with the increase of the service life, the bulletproof performance of the bulletproof vest is also constantly declining. The shelf life of bulletproof vest is affected by many factors, and it is very important to understand the factors that affect the efficiency of bulletproof vest for better preservation and prolong its service life. Normally, most bulletproof products can maintain a shelf life of more than 5 years. Very few bulletproof products have a shelf life of about 7 years due to the material. However, if it is maintained and paid attention to during use and storage, its validity period can be effectively extended, otherwise, even if the bulletproof function is rapidly reduced or even invalidated within the validity period, it is possible. So how to properly use and maintain bulletproof vest? 1.Regular cleaningTo prolong the service life of the bulletproof vest, it is very important to keep the bulletproof vest clean and clean. The bulletproof vest jacket can be washed in the washing machine, but it must be ensured that the bulletproof chip is taken out before putting it in the washing machine.When cleaning the bulletproof chip, you need to prepare a sponge and a small bottle of cleaning agent, use the sponge dipped in the cleaning agent to gently wipe the surface of the chip, remember not to immerse the chip in water, and do not use an ironing board to iron the chip wrapping cloth Because it is easy to burn the wrapping cloth accidentally, which will cause the chip to be eroded by air or moisture and stains during use, which will lead to a decline in the bulletproof function in the long run.   2. Avoid sun exposureExposure to sunlight accelerates the ageing of material fibers,  thereby reducing their service life and ballistic resistance.3. Usage frequencyThe bulletproof performance of the bulletproof vest is also related to the length of use. The longer the use time, the lower the bulletproof performance and the shorter the validity period. Therefore, if conditions permit, it is best to prepare a set of replaceable bulletproof vests, and two sets of bulletproof vests are used in rotation. It can prolong the service life of bulletproof vest as much as possible.   4. Replace damaged bulletproof vest in timeOnce the bulletproof vest is hit by a bullet, it should be replaced immediately, because even if the bulletproof chip hit by the bullet is not damaged in appearance, the strong impact will inevitably lead to changes in the microstructure of the material, thereby affecting its structural stability and ballistic performance. Replacement, then once the bullet hits the same position in the next use, the possibility of the chip being broken down will be greatly increased. Therefore, from the perspective of your own safety, the bulletproof vest that has been hit by the bullet must be replaced in time.The above is a summary of the precautions for the use of bulletproof vest. Only by giving the bulletproof vest proper maintenance during the use process can the validity period of the bulletproof vest be severely punished and its ballistic resistance can be maintained.

Overview: Anti-riot equipment, also known as police equipment, is one of the important categories of security products, mainly used for security, prevention and control work. Maintain social order and create a civilized homeland. It plays an important and irreplaceable role in building a harmonious society. Effect Anti-riot equipment is a special anti-riot weapon for riot police or public security officers when performing public security and anti-riot work, so as to effectively and quickly quell riots, solve emergencies that endanger public security, maintain social public order, and ensure social harmony and safety. Use Anti-riot equipment can reduce the harm to both parties in the case of suppressing riots and forcibly disbanding the crowds of demonstrations, that is, avoid harming the other side while protecting their own safety. Regardless of whether it is for riot police or riot crowds, in order to reduce casualties, special tactics or queues can be used, and professional anti-riot equipment can be used to deal with unarmed or low-armed people, in order to achieve the lowest hurt. Product Riot shield The riot police carry defensive equipment to resist foreign objects and people pushing. The protective area is larger than the round shield, and it is usually used by the riot control personnel in the first column. Riot Buckler The riot control personnel carry it as a light defensive shield, mainly to facilitate the arrest of criminals. Riot electric shield Lightweight defensive shield with aggressiveness. There are iron bars on the shield as a conductor. People who encounter it will feel pain. The power of this item comes from the battery. Anti-riot helmet Helmet equipped by anti-riot personnel. The opening method of the protective mask is different from that of general helmets. To prevent attacks, a two-stage opening method is designed.     Anti-riot suit Divided into conventional type and heavy loading type. They are divided into tops and bottoms. The heavy-duty clothing material has the function of fire prevention. The clothing has plastic and foam to absorb attacks. The design is dense and airtight, without any gaps. The airtight design also includes the neck, but there are some restrictions on movement. The regular type is light and easy to wear. Protective gloves heavy equipment equipped with anti-riot personnel to resist most joints of the hand from external attacks. Safety shoes The shoes worn by the anti-riot personnel are mostly made of military leather shoes.   In order to effectively prevent the expansion of violence, the non-lethal anti-riot weapons used: Strong dazzling light The dazzling light has a stroboscopic function. The strong light emitted will make the opponent extremely dazzling and unable to see the situation in a certain range around it. It has multiple functions such as rapid target discovery, strong light suppression, and psychological deterrence. Very suitable for the needs of night search and handling of special situations, Baton / Lathi It is divided into short cudgel and long cudgel. The short cudgel is usually used for arrest and is used with a round shield or a small square shield. The long cudgel is usually used for combat purposes but without a shield. Water jet truck: The car body is designed like a fire truck, loaded with a large amount of water, and uses the strong water pressure of the water column to repel. Anti-riot gun It shoots non-lethal rubber bullets, which makes people feel painful. It is often used in anti-riots around the world. Tear gas special for medium and long distances. It is made of chemicals that can dispense tear gas and stimulate tearing. It can be launched in the form of jet or grenade. Tear gas special for close-range riot suppression. The gas is loaded in a tank and sprayed by pressing, and the absorber is in the same state as tear gas. In order to prevent others from entering, protect their belongings and equipment of the house: Juma  Juma is an item used for the gates of military bases. It is also used in the anti-riot lineup to prevent others from entering (there are wire type and blade type). Snake cage An item that is not allowed to be entered by others. It is like a snake in a circle with a thorn or blade on the coil. There is also a snake cage loading vehicle, which can be quickly placed and retracted

A bulletproof shield, as the name suggests, is a shield with a certain bulletproof ability. The traditional bulletproof shield is a rectangular sheet-like object with an arc, usually with a handle on the back that is easy to hold. While defending against the enemy’s attack, just lift the shield in front of the user to cover the head and body, thus providing comprehensive protection for the user. However, with the continuous progress of the protection industry, various protection products are also changing with each passing day, and the functions, appearance and use design are also constantly improving, and they are more and more suitable for various usage scenarios and in line with human usage habits. There are many materials that can be used to make bulletproof shields, including aramid,  polyethylene, ceramics and steel plates.Bulletproof shields are generally classified by size and can be divided into ultra-small (450mm × 650mm), small (550mm × 650mm), medium (550mm × 1000mm), large (600mm × 1300mm) and super-large (600mm × 1750mm). Bulletproof shields also have strict protection standards. The National Institute of Justice of the United States has set 7 levels of bulletproof shields – Level I, Level IIA, Level II, Level IIIA, Level III, Level IV and Special class. Level I can protect against 0.22-inch pistol and 0.38-inch special pistols; Level IIA can protect against 0.357-inch Magnum and 9mm pistols (lower muzzle velocity types, such as 0.380-inch ACP bullets); Level II can protect against 0.357-inch horses Gnum and 9mm pistols (higher muzzle velocity types, such as 9mm Parabellum); Class IIIA can protect against 0.44-inch Magnum and 9mm submachine gun shots; Class III can protect against 0.308-inch Winches Special full armor and 7.62×39mm bullets; IV grade can protect 0.30-06 inch bullets, 7.62mm NATO standard bullets and 7.62×54mmR bullets; Special grade is customized for special bullets. There are many opportunities for SWAT to use bulletproof shields. However, since most of the SWAT police use medium-sized bulletproof shields, and sometimes tactical lights are added, they are basically IIIA-level, and III-level is also used when necessary, but the total quality of the two is very different. In terms of appearance and design, it can be divided into ordinary hand-held bulletproof shields, folding bulletproof shields, briefcase-type bulletproof shields, ladder-type bulletproof shields, and cart-type bulletproof shields. Hand Shield Handheld shields are usually equipped with 2 handles on the back, which can be used by left-handed or right-handed users at the same time, and are also equipped with bullet-proof glass viewing windows or sight glasses for easy observation of external conditions. Hand-held shields are mainly suitable for combat scenarios with complex terrain. For example, hand-held bulletproof shields are more flexible to use in narrower stairs or passages, and can also be better matched with weapons such as guns. Trolley Bulletproof ShieldThe cart type bulletproof shield is equipped with a cart, which is more labor-saving for long-distance movement. In addition, like the hand-held bulletproof shield, it is equipped with a handle on the back, which can be used by hand, and is also equipped with a bulletproof glass sight glass. Generally, shields with higher defense levels are usually heavy and require a cart for long-term use.The cart-type bulletproof shield is mainly suitable for relatively open and flat combat scenarios. When using, the shield can be moved freely over a long distance by placing the shield on the cart, which is more labor-saving. It can also be used by hand when the cart cannot be used due to changes in space and terrain. Ladder Bulletproof Shield There is a special structure behind the ladder bulletproof shield that can be turned into a ladder to deal with complex terrain, such as helping users to view and control the environment at higher altitudes when necessary. At the same time, the bottom of the shield is also equipped with wheels, which is more convenient and labor-saving to move. Briefcase Bulletproof Shield Briefcase-style bulletproof shields are bulletproof shields that look similar to briefcases. They usually look like a very common PR bag, but they can be quickly deployed into bulletproof shields in critical situations. The weight of this shield is only about 5 kilograms, and it has a good defensive effect on the protection of light weapons such as pistols.  

Traditional body armor can be roughly divided into three categories: hardware, soft, or soft-hard composite. In order to take into account weight, mobility and ballistic performance, the body armor widely equipped in various countries is mainly made of flexible aramid material, which is also high toughness and durability. Stretched fireproof fiber, the famous American Kevlar fiber is also one of them. However, in the National Institute of Justice (NIJ) designated by the National Institute of Justice, the general aramid material can only reach the IIIA level of protection, and can only withstand 9mm pistol bullets and 44-inch magnums at a certain distance. Bullets or pistol bullets with equivalent lethality, rifle bullets can still easily penetrate within the effective range. Check YF Protect bulletproof vest, please click this. Body armor with IIIA protection level is a very good choice for ordinary police. Its flexible material is not only comfortable, but also light in weight. It has little impact on personnel movements and can be worn for a long time during daily duty.   But this level of protection is far from enough for the military. If you want to defend against rifle bullets, the protection level of body armor needs to reach at least NIJ III level. The assessment standard for this level of body armor is: it can withstand six rounds of 7.62x51mm NATO standard rifle bullets with a muzzle velocity of not less than 847 m/s. This requirement has greatly exceeded the tensile limit of the flexible bulletproof material. Even if the high-strength flexible fiber can prevent bullets from penetrating, it still cannot offset the kinetic energy of fragments and projectiles transmitted to the human body through bulletproof vests during high-speed movement. If this kind of blunt injury is more serious, it can also cause people to die from organ rupture. Just before and after the millennium, my country introduced a large number of popular science documentaries recorded by Global Geography and Discovery Channel. There are many cases of policemen wearing body armor and being hit by bullets to break their ribs. And this is why there was a saying in the early years of "wearing a body armor and being hit by a bullet". Body armor cannot completely offset the damage to the human body caused by the impact kinetic energy, and serious fractures and organ damage may occur. In order to solve this shortcoming, bulletproof inserts used in combined aramid bulletproof vests were invented. The full name of the bulletproof insert is Small Arms Protective Insert SAPI, which is a ceramic individual bulletproof equipment that makes up for the short plate of flexible bulletproof materials. In 1918, British Colonel Newell Monroe Hopkins discovered that ceramic glaze can increase the protective performance of steel armor. The principle is similar to the carburizing technology (commonly known as surface carbon hardening) used by naval warships. Everywhere, the outermost layer of high hardness smashes the projectiles to disperse the impact stress on the armor. Hard body armor appeared during World War I Both the Soviet Union and the United States had vigorously studied ceramic armor during the Cold War, but due to technical and cost issues, ceramic materials that can be used for individual protection did not appear until the end of the 1980s. In the 1990s, the United States developed the first generation of bulletproof inserts made of alumina or silicon carbide ceramics. It not only reached the NIJ Ⅲ level of protection against rifle bullets, but also set off a revolution in the design of body armor. Prior to this, the function and composition of the body armor were relatively simple. To protect the level, weight and flexibility must be sacrificed. The emergence of bulletproof panels provides a combination of different protection levels. Soldiers can install a layer on the outside of the flexible body armor. Insert the plate to achieve a more comprehensive protection effect. The early bulletproof flaps were not light in weight, and there was a noticeable drag feeling when mounted on the body armor. The US military also believed that its ballistic performance was still not ideal, so it developed an enhanced protection kit (ESAPI). Enhanced protection kit This ballistic plate uses Aluminum oxide, Silicon Carbide or Boron Carbide with the highest hardness among all bullet-proof ceramic materials, which increases the protection level to an amazing NIJ IV level, which can withstand a 7.62 mm tungsten steel armor-piercing warhead. Excellent performance naturally means high cost. The cost of a single ESAPI is as high as $300 in USA market. but from our YF Protector, you can buy a plate with only 1/6 of the price, contact us (operation@yfprotector.com) to know more details.  

In daily life, if we are careful enough, we will find that many skyscrapers, truck covers, oil platforms, and bulletproof equipment have a common material – polyurea. The popularization and promotion of polyurea is said to have originated from the experiments of a group of Italians. They tried to free fall the polyurea-coated watermelon from a height of 45 meters, and the watermelon bounced back when it landed, and its appearance was intact. In order to further verify the protective ability of polyurea, some people also tried to spray polyurea on eggs and tested, and the eggs were also intact. With its excellent protective properties, polyurea has become more and more widely used in various fields from heavy industry to agriculture, especially in the field of protective products, its application is also more and more promising.   Polyurea is formulated from specific raw materials in a specific proportion. Its specific material formulations are kept secret commercially, but the basic ingredients can be identified as a combination of isocyanate and polyol resin. Polyols primarily act as plasticizers, and when the two components are combined, they polymerize to form a long-chain molecule. Long chains of molecules are intertwined with each other to form an indestructible material called polyurea. In addition, these long-chain molecules are stretchable and have high flexibility, which also endows the polyurea material with ultra-high tensile and tear resistance.   In addition, polyurea has many performance advantages, such as:Quick-drying – Polyurea coatings sprayed on surfaces such as various instruments and equipment can be dried and set in seconds and are ready for use.Very high wear and compression resistance.Good chemical resistance.Super airtight and waterproof.Does not contain VOCs, CFCs, solvents, etc., and does not cause any pollution to the environment.   It is precisely because of these characteristics of polyurea that it has a lot of attention to its use method and application. At present, polyurea is usually coated on the surface of objects by thermal spraying, which is time-critical because once the two components of the coating are combined, the reaction starts immediately and cannot be reversed. In the process of use, the two coatings need to be pressed into a special spray gun through a heated hose, the two are quickly mixed at the moment of spraying, and then quickly dried and formed in a few seconds.

  Introduction of Bulletproof Clothing Bulletproof clothing is one kind of personal protective military uniform used to protect the human body (most important the human chest and abdomen, Vital organ) from bullet, projectiles or shrapnel, mostly in the shape of a vest, composed of inner bulletproof layer and outcover. Soldiers dressed with ballistic clothing can significantly reduce the mortality and injury rate in the field.   Development of Bulletproof Material During the First World War, 80% of the total casualties on the battlefield were caused by low- and medium-speed stray bullets or fragments of bombs. Experts were inspired by ancient armor and developed the first generation of bulletproof clothing at the end of the war. In the Second World War, the casualties caused by shrapnel still accounted for about 60%. People paid more and more attention to the development of bulletproof clothing. In the early 1940s, the United States and some Western European countries began to develop alloy steel and aluminum alloys. In the 1960s, second-generation bulletproof clothing that replaced high-quality steel with high-quality chemical fiber materials began to appear. After the 1970s, bulletproof clothing had new developments with ceramic material which make the bulletproof protection level reach the highest. In a word, Body armor can be divided into three types: soft, hard and composite. The material of soft body armor is mainly made of high-performance textile fibers. These high-performance fibers have much higher energy absorption capacity than general materials and endow the body armor with bullet-proof functions. And because this kind of body armor generally adopts the structure of textiles, it has considerable the softness and protection. Hard body armor is originally made of special steel plates, aluminum alloys which are replaced by ceramic materials like aluminum oxide, silicon carbide and other hard non-metallic materials. The body armor made from this generally does not have flexibility.   The softness of the soft and hard composite body armor is between the above two types. It uses soft materials as lining and hard materials as panels and reinforcement materials. It is a composite body armor.   Detailed Info Need Known when Purchasing Bulletproof Vest Bulletproof vests are a special type of personal protective equipment, mainly made of bulletproof material, designed to provide body protection and reduce or avoid attack from firearms, knives and other weapons. At present, bulletproof vests have been widely used in military, police, special forces, security, anti-terrorism and other fields. The following is a detailed introduction to the key words of bulletproof vests. First, bulletproof material. There are many kinds of bulletproof materials used in bulletproof vests, such as polymer materials, metal materials, composite materials and so on. Among them, fiber material is currently the most widely used one, such as polymer polyethylene fiber, aramid fiber, ultra-high molecular weight polyethylene, etc., these materials have the advantages of lightweight, durable, flexible and so on. Second, bulletproof standards. The bullet-proof capability of bullet-proof vests needs to be tested and evaluated by special bullet-proof standards, such as NIJ 0101.06, EN, GA, etc. When purchasing bulletproof vests, you need to select the corresponding bulletproof grade and certification standard according to the actual demand. The third is the anti-cutting material. In addition to bulletproof features, some bullet-proof vests are also designed to prevent stabbing and cutting. Anti-stabbing cutting materials generally include metal mesh, glass fiber, ceramic plate and so on. These materials can effectively resist knife attacks and provide more comprehensive body protection. In addition, the certification of bulletproof vests, debris protection, hard bulletproof plate, soft bulletproof materials, accessory configuration and wearing comfort are also important factors to be considered when buying bulletproof vests. In actual use, all kinds of factors need to be considered comprehensively to choose a suitable bulletproof vest. To sum up, bulletproof vest is a very important personal protective equipment, for the personnel who need to carry out high-risk tasks, has an irreplaceable role. When buying a bulletproof vest, you need to fully consider various factors and choose the right vest for you.   Ballistic Performance The ballistic performance of body armor is mainly reflected in the following three aspects: 1. Anti-pistol and rifle bullets At present, many soft body armors can protect against pistol bullets, but to protect against rifle bullets or higher energy bullets, ceramic or steel reinforced plates are required.     2. Bulletproof debris. High-speed fragments produced by explosions of various explosives such as bombs, landmines, artillery shells and grenades are one of the main threats on the battlefield. According to investigations, the order of threats faced by soldiers in a battlefield is: shrapnel, bullets, blast wave, and heat. Therefore, the function of the protection against bulletproof debris must be emphasized.     3. Prevention of non-penetrating damage. The bullet will produce a great impact after hitting the target, and the damage produced by this impact on the human body is often fatal. This kind of injury does not show penetration, but it can cause internal injuries, and severe cases can be life-threatening. Therefore, preventing non-penetrating damage is also an important aspect of the ballistic performance of body armor. Contact us if you want to know more details or purchase Bulletproof vest!

The suspension system of a bulletproof helmet refers to the arrangement of straps and padding that hold the helmet in place on the wearer’s head. There are several different types of suspension systems used in bulletproof helmets, and they differ in their design and functionality. Here are some of the most common types:1. Fixed suspension system: This is the simplest type of suspension system, consisting of a fixed set of straps and pads that hold the helmet in place on the wearer’s head. This type of suspension system is commonly used in older or less expensive bulletproof helmets.2. Adjustable suspension system: This type of suspension system allows the wearer to adjust the fit of the helmet to their head size and shape. It typically consists of a set of straps and pads that can be moved and adjusted to create a comfortable and secure fit. 3. Modular suspension system: This type of suspension system allows the wearer to customize the fit of the helmet to their specific needs. It typically consists of a set of removable pads and inserts that can be arranged and adjusted to create a custom fit. 4. Ratchet suspension system: This type of suspension system uses a ratchet mechanism to adjust the fit of the helmet. It typically consists of a set of straps and pads that are connected to a ratchet system that can be tightened or loosened to create a custom fit. 5. Dial suspension system: This type of suspension system uses a dial mechanism to adjust the fit of the helmet. It typically consists of a set of straps and pads that are connected to a dial system that can be turned to tighten or loosen the fit of the helmet. Overall, the main difference between these suspension systems is their adjustability and customizability. While a fixed suspension system may be adequate for some wearers, an adjustable, modular, ratchet, or dial suspension system may be necessary for others to achieve a comfortable and secure fit.
