Tear-offs help you maintain a clean field of vision in muddy conditions. You can stack as many tear-offs as needed to increase your number of pulls. Running a single tear-off in dry conditions can also be beneficial as it helps protect your lenses from scratches. This can be especially useful for off-road riders who face trail overgrowth and loose terrain. Tear offs should be mounted so that the pull tabs are on the riders left sideFor use with Fox Vue goggles only20 pack included
