Our AR550 body armor is NIJ level III rated but has undergone special threat testing to achieve a level III+ rating, click here to learn more. NIJ Certification applies to AR550 Shooters and Swimmers Cut Single Curve Full Coat armor plates. 


Why Are Your AR550 Single Curve Full Coat Plates Labeled as Level III? 


Spartan AR550 Single Curve, Full Coat body armor plates are labeled as level III on the back of the plate as the National Institute of Justice (NIJ) does not currently have a level III+ rating. Level III+ indicates special threat testing and was created by the body armor industry to fill the void between NIJ 0101.06 level III and NIJ level IV, specifically to account for high velocity penetrator rounds such as M855 (aka green tips). While Spartan AR550 single curve full coat plates are certified as NIJ level III, rest assured they are made from AR550 ballistic steel and have been special threat tested to level III+. Quite simply, the NIJ requires that we label AR550 single curve full coat plates as level III even though they are capable of higher ballistic protection.



The Hydra Plate Carrier is a highly adaptable carrier ideal for quick deployment and emergency situations such as active shooter scenarios. Easily adjustable buckles ensure a snug and comfortable fit on the sides. Ample length shoulder straps allow the Hydra plate carrier to be easily adjusted to fit a wide variety of body types. Breathable mesh is used at chest, back and shoulder contact points to allow for maximum breathability. The Hydra plate carrier is a great choice for anyone looking for a lightweight and versatile body armor configuration.

Coating Options: 

Choose the Full Coat option to have the plate lined with 1/4-3/8 of our proprietary coating, Encapsaloc ™.  The result is a plate approximately 1/2-5/8” total thickness.  See our FAQ for more information about our Encapsaloc ™ process. The base coat option has an extremely thin layer of our fragmentation mitigation coating to aesthetically enhance the plates, and to provide corrosion resistance. This coating has minimal, if any, fragmentation mitigation capabilities.
