Product Description: 
DECISION LAYER This forms the first and most essential layer of the system. It cools when you sweat and warms when you're cold. With higher levels of activity, a thin, cooling film of moisture is maintained while excess sweat is wicked away. With light activity, the Decision Layer insulates. The result: The body remains perfectly regulated and the athlete is able to perform powerfully for longer.
