This extended jacket has 450 layers of synthetic insulation and a thermally reflective lining to warm you up. The thermoreflective lining has silver dots charged with heat, which consequently warm up the inside of the jacket, while the upper material wicks moisture away and evaporates sweat and moisture. When the wind strikes, protect yourself with a hood. The two-way zipper lets you easily reach lower layers of clothing or ease up ventilation.
