Sleek new iteration of the J29 blazer featuring an HD Nylon face fabric and Polartec® Alpha® insulation. Built to work standalone or as a modular insulator. DFMA shoulder for drop bars. Holster pockets for low-observable storage. The J29 convertible revers shields up or suits down. More stylish than anything this technical has a right to be and vice versa. 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 for shedding or adding layers while on the move. A highly compressible fabric, it easily layers with other materials and is storable in small spaces. A stable core of lofted knit fibres prevents fibre migration to keep a uniform consistency, even after heavy wear and repeated laundering.
