This 1 of 1 IcePlate EXO® prototype plate bag is made out of Coyote Brown nylon. It is NOT made out of our proprietary HMWPE laminate like the production IcePlate EXO®. This prototype has a a removable OneWrap plate retention flap at the bottom and Tegris ATAK Reinforcements on the center chest. The Tegris ATAK reinforcements did not make it to production because our laminate is so strong that it doesn't need them. This sleeve would be ideal to use in place of IcePlate® Sleeve and pair with an existing IcePlate EXO® to carry an IcePlate® Curve.
