With this one tube scarf aka Buff, you get a balaclava, bandana, hat, and a dust-proof mask all in one. Stretches well and dries off quickly. The synthetic Power Dry material from Polartec® traps the heat to keep you warm, retaining breathability to prevent sweating and irritation. Can act as a wind shield while running or skiing, covering your face and neck. Also works great as a part of your cycling or motorcycling gear.
