The Insulation

Polartec® Alpha® was originally developed for the U.S. Special Forces when they required a more advanced insulating material in their combat uniforms. This fabric is a new technology with active insulation that regulates core body temperatures during both dynamic and static activities. This latest advancement in adaptable breathability helps eliminate the need of shedding or adding layers while on the move.
