Buff Merino Wool Balaclava offers excellent breathability and is naturally water repellent, anti microbial and elastic. The new improved Balaclava Microfibre BUFF has a laser cut mouth port which helps to reduce perspiration, avoiding humidity for breathing and reduce goggle fog. It's also lightweight and super soft. Balaclavas are ideal for really cold conditions and when there can be a risk of frostbite. The Buff version will fit snugly under a motorcycle helmet or a climber's, giving maximum protection for the head, face and neck.
