Polartec® Alpha® was invented for the U.S. Special Forces. They required a superior insulation system for extreme temperature variations and the start-stop conditions of combat. Alpha® active insulation is engineered for consistent warmth, while allowing greater breathability during activity. This air exchange technology creates sustained comfort without shedding layers, which isn’t an option during a mission. Polartec® Alpha® active insulation continuously releases excess body heat before it builds. This patented, adaptive quality is made possible through Alpha’s lofted fibers connected to a solid mesh core. Since Polartec® Alpha® is inherently hydrophobic, it resists all moisture and dries incredibly fast.
