It doesn't get any better than the GOX Zip Off system when it comes to keeping the dirt and mud off your lens. The EKS BRAND Zip Off's come standard with two rolls of ultra thin film, an anti-fog coated, GOX lens to help prevent any condensation or fogging. Two Zip Off canisters, a motor side and a spool side and a moisture visor to keep dirt and wetness from penetrating under the film. The XBRAND Zip Off's allow the rider to have nearly 35 pulls of clear vision to get through a race or a long day of riding.
