Our panted combat shirt is constructed and designed using knitted sleeves and body to help decrease weight and increase breathability. What sets the Extreme Hot Weather DBL apart is our Air One (A1R) Commando body fabric. Advanced lightweight FR Modacrylic & FR Rayon Mesh that allows air to freely pass through, it provides unsurpassed lightweight breathability in the most extreme hot weather conditions. Perfect under your plate carrier to add breathability, moisture management, and antimicrobial/anti-odor in extremely hot weather conditions/environments. Patented blend of fibers for lifelong FR protection means our FR protection will not wear or wash out. It is there for the life of the garment. With built-in elbow/forearm protection, no need to insert elbow pads. Designed to contour to the body with a full range of motion while allowing for unrestricted movement.
