Lightweight Thermal protection. Originally created for the unique needs of the U.S. Special Forces operating in extreme temperature variations, Polartec Alpha Direct is able to offer superior thermal protection through the lofted fibers connected to a solid mesh core.

By refining the shape and size of its lofted fibers, Alpha® Direct can be in direct contact with skin or other fabric layers. This new design ability increases breathable performance, expands versatile style options, and further reduces overall garment weight.
