Buff ® Original Buff®
Very versatile. I use it as a sweatband on my wrist sometimes and it is great at tying back all my thick hair in numerous variations, while wicking sweat away. It provides enough warmth around the ears on a chilly day, but not too much that you start to get itchy and irritated mid-run. I have even used it as a visor when the sun came out unexpectedly. Would recommend.
