Features like knitted sleeves - reducing weight while increasing mobility/breathability, built-in elbow/forearm protection requires no need to insert elbow pads to help warfighters worry less about their gear and more about the mission at hand. Aimed to contour to the body with a full range of motion while allowing for unrestricted movement. Breathability, advanced cooling moisture management, and antimicrobial/anti-odor protection make this a must under any vest/plate carrier in the hottest of environments.
