Forget sweat. Stay dry and focused. Skip the drips. This is the ultimate sweat control skullcap, with a best-in-class guarantee. SweatHawg Skullcaps combine quick-wicking lightweight hygienic bamboo fabric with a doubled hyper-absorbent brow to stop runaway perspiration. Absorbency gathers excess sweat, wicking disperses it, and evaporation cools. Flat seams mean no "hot spots" when used under a helmet. Convenient, comfortable, and effective for all hard exercise and every sweaty activity. Use under a helmet for team sports like football, hockey, and lacrosse. Take one running, skiing, cycling, and climbing. And they go to work in construction, welding, wildland firefighting, and hot kitchens. Side benefits: hides wild hair, shields your head from direct sun. This version of our skullcap covers the tops of ears on most.
