Mission Athletecare Enduracool Instant Cooling Helmet Liner
The first ever cooling skull cap. Constructed from a new proprietary cooling material to custom form to the head and maximize the cooling effects. This new performance fabric instantly cools when wet, wrung out and then snapped in the air to activate the cooling properties.  It works by absorbing moisture and perspiration into the fabric core where the unique radiator-like fiber construction circulates water molecules and regulates the rate of evaporation to create a prolonged cooling effect.
