Polartec® Alpha® Direct, a recycled synthetic fill that is remarkably warm for its weight and density. Polartec Alpha Direct has an incredibly high rate of moisture vapor transfer due to its highly open structure and lack of backer fabric.
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.
