This neck gaiter packs many punches in terms of functionality, durability, performance, and sustainability. It provides breathable, lightweight coverage for your face and neck (but can also be worn as a sweat-wicking head or hair band), while offering UPF35 protection from the sun. It's naturally odor resistant and has superior moisture-management properties, making this a great option for an active performance lifestyle. In terms of sustainability, the TENCEL™ Active cellulosic fibers are derived from renewable wood sources and the tube is 100% biodegradable.
