Bullet Resistant Vest & Bullet Vest

Bullet Resistant Vest

Bullet resistant vest, also known as ballistic vest or body armour, are made from multiple layers of high-strength material and have various specifications:

Material	Kevlar, Dyneema, Polyethylene (Kevlar is lighter than steel).
Protection	Bullet resistant vest should provide 360-degree protection and be able to withstand multiple hits.
Flexibility	The vest should be flexible enough to allow for freedom of movement and a snug fit
Closure	The vest can have a zip or Velcro closure
Emergency release	The vest should have a quick-release mechanism in case of an emergency
Comfort	The vest should be adjustable for comfort and loading-bearing capability
Water resistance	Some vests are encased in water-resistant nylon to prevent liquids or humidity from entering
Ballistic resistance standards	The National Institute of Justice (NIJ) has standards for ballistic resistance, including NIJ Standard-0101.07, which outlines testing procedures, and NIJ Standard-0123.00, which describes ballistic protection levels.

Protection Level

Class	Weapon / Ammuntion	Range	Velocity	Shots
B2	9mm	5	400m/s	3
B3	357 magnum	5	430m/s	3
B4	44 magnum	5	440m/s	3

Bullet Resistant Vest (Stab proof) :

The selection of materials is critical in the effectiveness of stab vest. High performance fabrics, such as aramid fibres (Kevlar) or ultra-high-molecular-weight polyethylene (Dyneema), are commonly used due to their exceptional strength and resistance to knife penetration.

Bullet Resistant Vest (Heat proof) :

Material	Kevlar
Protection	The vest should protect against heat, water..
Fabric weight	The fabric weight should be at least 95 grams per square meter
Closure	The vest can have a zip or Velcro closure
Breathability	The vest should be breathable and comfortable.
Testing	The vest should be tested for its ability to withstand heat, water
