I wear a lot of neck gaiters when hiking and biking, since they are so versatile, from warmth under the hat/helmet to sun and wind protection to keeping my hair out of my eyes to looking like a pirate. This one surprised me in a good way. The material is more like a polyester than a cotton feel, but was comfortable and light. I really liked the bike wheel/poppy design. I'd give it 5 stars.
