The insulating fabric made with Coolmax® technology for all stations transports moisture away from the body to keep the user fresh and dry on hot days, while fiber structures provide heat on the coldest days, which helps optimize the performance. Fiber micro channels allow air circulation when body temperature increases, which helps thermal regulation.

Polartec® Classic tissues are the reference standard for light heat and breathability. The construction of the 100% polyester polar lining creates airbags that catch air and body heat. Unlike other polar lining fabrics, Polartec® Classic products maintain their insulating capacity and not pilling after repeated washing.
