Kevlar (para-aramid) [2] is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora.Developed by Stephanie Kwolek at DuPont in 1965, [3] [2] [4] the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires.
Fabric panel (level II protection) in the back is made of 30 layers of TSVM-2 Kevlar-like material and provides protection against bullets from TT pistol (cartridge 57-N-134S) and PMM (cartridge 7N16) from 5 meters, has increased anti-fragmentation resistance (fragment weighing 1 g at a speed of 600 m/s, 50 %,).

The Improved Outer Tactical Vest (IOTV) in MultiCam, as issued to United States Army soldiers. A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armor designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso.
The fiber is an evolution of the original Kevlar fiber. The following quotes summarize Kevlar KM2's properties. "DuPont created Kevlar KM2 to achieve the performance goals defined by casualty reduction testing for the United States Department of Defense. Today it is used extensively for fragmentation protection in the U.S. military. Helmets and ...
The term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location, or simply sufficient kinetic (movement) energy to overcome it.
Due to the various different types of projectiles, it is often inaccurate to refer to a particular product as "bulletproof" because this suggests that it will protect against any and all projectiles. Instead, the term bullet resistant is generally preferred. Standards are regional. Around the world ammunition varies and armor testing must ...
Here are the most important items to put in your emergency kit. The use of a rubber bullet is one of the more controversial crowd-control measures, says Robert Glatter, MD, an emergency physician ...
The OTV features a carrier shell, and three main (flexible) ballistic panel inserts (front left and front right panels, and a rear back panel), [4] which are made with a finely woven Kevlar KM2 fiber. These two parts of the vest are both bullet and heat resistant and offer protection similar to the earlier PASGT flak jacket.
