    AirShield Elite is used in our most premium windproof products. It offers the most comfortable level of breathability by combining high moisture-vapor transfer rates and air permeability at all body temperatures. Traditional wind barrier membrane technologies require high levels of user exertion (high body heat) before the breathability kick in. Like Dry.Q Elite, AirShield Elite is an instant-on technology. It starts breathing the minute you put it on, regardless of temperature or level of exertion, so you stay drier and more comfortable.
