This lightweight neck gaiter keeps out the cold when hiking, biking and running. With a UPF50+ rating, the fabric is also designed to reduce sun exposure. Soft gauze material on the inside pairs with breathable polyester jersey fabric for comfort during training sessions throughout the year. And polyester’s durability means you can wear this neck tube season after season. With its light weight, this neck warmer is ideal for stashing in your pocket, ready to slip on while you rest at the summit or during a wind-blown descent. The unisex Brand Neck Tube is a multi-season staple for extra warmth and coverage.
