Made from Turtle Fur's proprietary Comfort Shell™ material, it provides full coverage for your neck, ears, and head, with partial face coverage without trapping moisture. The fitted neck sits comfortably around the clavicle and includes extra fabric to tuck into jackets and base layers. Breathable, sweat-wicking, and lightweight, the MaxClava is perfect for wearing under a helmet and goggles or a warm hat while skiing or enjoying other cold-weather activities.
