Big Mak GTO Budget AirBag with Tank Rack 4" tall, 11.5" long, 6" wide. The Goat budget bag is a perfect way to get a "feel" for how the AirBag system works, and to use as a "city" bag to switch out with a larger AirBag when you're traveling. The GTO doesn't have the mesh side pockets or interior Velcro dividers, but it does have an integrated map pocket on the lid. The zipper isn't covered by a flap like on the other AirBag models, but a rain cover is included so weather won't be a problem. Not compatible with most of the AirBag accessories (map cases, pockets, etc.) - this is a stand-alone bag. Rack #BMA-3-BW5 @ $69.95, Bag #BMA-1-GTO @ $79.95	$149.90
