Using cutting edge materials technology our Hybrid vest is at the forefront of concealable armor. Our 3D Spacer mesh allows heat to escape from the body, keeping the wearer cool in warmer climates and extended wear. It also results in the wearer having a very high level of comfort. The HYBRID was specifically designed to be lightweight, comfortable and cool, while offering protection from a range of threats.

Edged Blade Levels

While the NIJ is considered the world standard for ballistics testing, stab-proof vests are standardized by the CAST. Many assume that if a piece of body armor can stop a bullet, it can stop a knife. This is not the case however, and stab proof vests are different in make up to bullet proof vests. It is possible to find multi-threat vests that can protect against both, but these still need to be graded according to the protection they offer against both bullets and edged/spiked weapons. The threat levels for stab proof vests are standardized by the CAST as follows:

Knife Resistant Level 1 Knife Resistant Level 2
Energy Level E1 E2 E1 E2
Energy (joules) 24 36 33 50
Velocity 5 m/sec 6.2 m/sec 5.9 m/sec 7.3 m/sec
Total Missile Mass 1.9 kg 1.9 kg 1.9 kg 1.9 kg
Maximum Penetration 7mm 20mm 7mm 20mm


There is also spike protection to be considered, which was first introduced into CAST’s standards to address the additional threat faced by Prison Officers. Spike protection can be added to stab and ballistic vests, neither of which will ordinarily protect against spiked weapons. CAST will only certify spike protection in addition to stab protection. The threat levels for spike proof vests are standardized by the CAST as follows: 

KR1 & SP1 KR2 & SP2
Knife Resistant Level 1 & Spike Protection Level 1 Knife Resistant Level 2 & Spike Protection Level 2
Energy Level E1 E2 E1 E2
Energy (joules) 24 N/A 33 N/A
Velocity 5.0 m/sec N/A 5.9 m/sec N/A
Total Missile Mass 1.9 kg N/A 1.9 kg N/A
Maximum Penetration KR1=7mm, SP1=0mm N/A KR2=7mm, SP2=0mm N/A
