Polar Buff® Reversible is a 2-layer garment made from a seamless tube of Polyester Microfibre sewn top and bottom to a tube of fleece. This creates an air cushion, providing extra protection and helping to maintain body temperature. It can be worn in a wide variety of ways. Polar Buff® Reversible can be worn as a neckerchief, mask, balaclava, scarf or sahariane with either side on the outside or just part way.
