                  *Sold Individually, Select Qty 2 For A Pair


Our III+ MODEL 3812 plate is a very good choice for those who are looking for high level of protection on a low weight and stoppage capability. It can be used in a low profile plate carrier and it’s a great option for both males and females as its anatomic curvature serves to provide best comfortability and protection from small to medium size rifle ammunition, even against armor penetrator options.


Since this plate is multi-hit rated you can expect it to protect you from 9mm to 7.62×54 (LPS)  including M855 rounds. Backface deformation is a very important factor that everyone should know about because even if a bullet does not penetrate the plate, you will still feel the kinetic energy and can still cause bodily damage or harm on impact. Keep in mind that we test all of our armor to the maximum standards or so-called “worst case scenario” situation and BFD (backface deformation) on model is highly common as with any other different body armor. This is why we offer an additional IIIA soft armor plate as a backer which can be inserted separately in our Prime Warrior Plate Carrier 3.0.
