Free Your Hands: Our beanies will keep you warm and stay secure while freeing you up to do the work you need to do. No longer do you need bulky, headlamps that fall off or loosen up while you’re on the move. Our batteries are secured so you can run, jump, bike, climb, etc without worrying. The knitted cap provides a cushion, which means you won’t feel the battery pack or LED bulbs on your head.
