Within the ASSOS winter jacket collection, the shaQ is unique, featuring a double-face construction. Layer ONE, the next-to-body layer is made of the legendary ASSOS RX soft fleece bi-elastic material that contours to your body the way you want and need it to. This layer offers superb insulation and advanced moisture-wicking properties. Layer TWO is a body-mapped protection shell. These two layers are NOT bonded but strategically attached, creating a sensation of total freedom of movement. The size of the layers is slightly different, each carefully calibrated to create an air chamber between the layers that functions as a heat regulating system. Excess moisture is transferred effectively to the outside by the jacket's ventilation system.
