Sweating sucks, but everyone does it. It smells, it stains, and worse off, it can sting if it gets in your eyes. So our techies here at Triple Eight listened to our top riders, went back to the drawing board and developed the patented Sweatsaver liner that helps eliminate all of that. Our revolutionary liner has moisture-wicking layers that limit sweat drippage, anti-bacterial treatment to make it virtually stink proof, and a 360 wrap around design so that there is absolutely no liner separation. And with our terry cloth construction, you can kiss that itchy head feeling goodbye. Our Sweatsaver liner is standard.
