Fashion, Apparel and Garment Design Smart Breath Down Ski Jacket by Bosideng Global Innovation Institute Based on the distribution of human sweat and heat, combined with aerodynamics, as well as high-tech materials and special structural design, the designers have innovated the smart breath system. During physical exercises, the hot and humid air is gathered and distributed to the specific heat dissipation area through the airflow channels. At the same time, the externally adjustable channels allow the cold air to enter the inside, thereby forming an air circulation in the clothes.
