The Crazy Idea Fast Cut Thermo headband is a simple piece of Vuelta, a soft, moisture-wicking, bacteria-resisting fabric. If you’re lazy about washing your head gear, the “bacteriostatic” treatment should delay the onset of “stink”. The band is designed for skimo racing and other highly aerobic winter sports. Choose from two sizes (men: think large) and plenty of colors to fit stylishly under your helmet. Weighs 14g [L].
