The MASS Hilo IIIA Ballistic Insert Set is a great way to armor up your Hilo Carrier with NIJ Compliant IIIA armor.  You can easily run the carrier with just the inserts or along side your plates for extended coverage as well as ability to level up your III, III+ or ICW ballistic plate.

All our inserts are made from 100% Kevlar that is quilted and then sealed using the ultrasonic sound process of Sonobond for ultimate protection from UV, debris and completely waterproof.  Since it is made from 100% Kevlar it will last longer than other mixed aramids while also being a tried and tested solution.
