Smith Optics Universal Roll-Offs Kit

The Universal Roll-Offs Kit from Smith Optics ensures that you will have continuous clear vision with your goggles no matter how muddy it gets on the trail. Once the two canisters and a visor are attached to your goggles, insert the film cartridge into the right cartridge to spread a thin layer of clear plastic over the lens. When that mud splatters, pull the roll to dispense a clean layer of film and discard the dirty film into the left canister. Simply install, ride, and roll off that mud.
