Made from a top quality UV-treated Tri-Max ballistic nylon, this bag is contoured to fit on most tanks, including sloped Adventure models, and features a protective base material that prevents slipping or marking. Mounting is quick and extremely secure using new adjustable low profile hooks that attach to the bag, while webbing soft ties anchor to or around the bike’s frame. Each bag maintains shape when empty and includes reflective piping, a lined interior and an office organizer under the lid. It also features a convenient clear map pocket and an integrated GPS/smartphone pouch on the lid. When more room is needed, the bag is fully expandable, adding an extra 4 inches of height and increasing the capacity to more than 21 liters. This product includes a lifetime "no hassle” warranty, an expandable waterproof rainstorm cover with clear top, and is available in black and hi-visibility yellow.
