Mission Enduracool Instant Cooling Towel Stay cool in the heat of competition. Mission’s™ Enduracool™ is made from a proprietary performance fabric that instantly cools when wet with water or sweat, wrung out and snapped in the air to activate the sustained cooling properties. Use during or after competition to provide sustained cooling on your neck, head or other hot zones. How does it work? A revolution in cooling, this performance fabric absorbs and retains sweat and water, circulating the molecules while regulating the rate of evaporation to ensure an instant cooling effect against the skin for hours, without feeling wet. Cooling properties lasts up to 2 hours and the towel also offers wearable Ultra Violet Protection factor (UPF) 45 provides sun protection when covering the skin. This lightweight, chemical-free 80% polyester/20% nylon machine washable is engineered for all sports and when not activated for cooling, wipes away water and sweat, providing a great way to keep dry during an intense workout. Towel dimensions: 12.25" x 33".
