For low-profile headwear that will keep out the cold, a beanie, skull cap or watch cap keeps you warm without hindering performance. The watch cap is a closely fitted knit hat that got its name from sailors in the U.S. Navy, who would wear this hat while standing watch. The watch cap remains approved for Navy use in cold weather conditions. A beanie, skull cap or watch cap provides a close fit that lets you maintain a covert look and can fit under a hood or helmet. Some styles come with performance features such as a small zipper storage pocket that can hold a key or other small items, flame-resistant construction, lining to absorb and retain body heat and moisture-wicking technology. Stay dry, warm and comfortable in the dead of winter with a beanie, watch cap or skull cap.
