Lightweight enough to roll up and carry in a jacket pocket, this Ussen Flight Hat is effective and convenient thermal layering headwear, designed to be used on its own or under a helmet. This double-layered, woven polypropylene thermal hat has very fast wicking properties, with a long turn up that can be pulled right down over your ears and back of your neck in colder conditions. This British-made hat is part of the Ussen range of thermal layering clothing, including Multitube Neck Gaiter, Thermal T-Shirts and Long Johns, all available here at SockShop! (02/13)
