The Kayan Neck Gaiter is designed to keep you warm in the cold, and will also wick moisture away from your skin to keep you cool when it's hot. This versatile little guy can act as a scarf, a beanie, a sweatband, a face veil or any number of other creations you can think of. The Kayan is something you probably never knew you needed until you own one, and then you won't be able to live without it.
