Improved comfort and fit is a distinguishing factor between single and multi-curve ballistic plate designs. The more comfortable the armor is to wear, the more likely it is to be worn. Multi-curve models bullet proof plate are designed to fit more ergonomically and anatomically when positioned against the human torso. This translates into an improved range of motion and longer wearability in the field. We YF PROTECTOR offers both single and multi-curve models ballistic plate to accommodate most any budget.
