"Our renowned Brainsaver rubber helmet is one of the best multi-impact helmets available. This helmet is not for bicycle use. Our 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 our terry cloth construction, you can kiss that itchy head feeling goodbye. Our Sweatsaver™ liner is standard in all rubberized helmets and pro helmets, and is also sold individually in sizes XS – XL."
