This helmet can be used as necessary protective gear for skateboarding, in-line skating ("rollerblading"), roller derby, and scooters. This helmet is not for bicycle use. The patented Sweatsaver liner helps eliminate the smells, the stinging and the eye blurring that occurs from sweat. This revolutionary liner has moisture-wicking layers that limit sweat drippage, an anti-bacterial treatment to make it virtually stink proof, and a 360 wrap around design so that there is absolutely no liner separation. With the terry cloth construction, you can kiss that itchy head feeling goodbye.
