The Triple 8 Replacement Visor is a CE certified Impact-Resistant Polycarbonate protective lens that does not affect your vision while protecting it. They are of course a replacement visor if you somehow manage to break the visor on your Triple 8 Certified Sweatsaver Helmet with a Visor but you can also customize your look or get some more shade to your eyes with the tinted version. They are made with Hi-Definition optics for distortion-free optical clarity as well as anti-scratch and anti-fog coatings to keep the lens clear. Integrated Venting Channels also make sure that the lenses aren't fogged up from your body heat or breath while skating.
