Light and warm fleece hat for cool and cold weather from M-TAC. CapThe hat is made of microfleece, which makes it much lighter than any, even the finest wool. It does not "gain" moisture, dries quickly. And also prevents itching and irritation (which is wrong with wool or polycotton). The low-profile construction easily fits under a helmet and a hood.
