A range of replacement lenses, roll-offs, tear-offs, outriggers etc are available for the Oakley Airbrake MX Goggles.
Clear Lens: OA-57-993
The Airbrake Roll-Off Kit (OA-100-258-001) has a new larger canister, which means a new longer roll-off film (the old film can still be used), new longer design mudflap, easier door opening and 50mm roll-off film.
The part number for the new bigger film rolls is OA-102-855-001 (which are also for the Front Line goggles). The part number for the old roll-off film is OA-100-259-001.
As well as replacement foam being available, Oakley also do a "Sand Accessory Kit" and a "Snow Accessory Kit", both of which use closed cell vent foam for the Airbrake goggles.
