Rocky Mountain Saddle Bags by Wolfman Luggage are spacious, made of high quality material and come with waterproof liners. The bags have strong durability based on vinyl-coated 1680 denier ballistic nylon. Waterproof liners made of polyurethane-coated nylon with sealed seams keep your gear dry. Since the liners are yellow, items in your bag disappear less easily. The bags have a capacity of 32 liters. Dimensions are 16 inches long by 10.5 inches wide at the top, becoming slightly smaller at the bottom for simpler packing and unpacking. Features added to the Rocky Mountain Saddle Bags include a secure mounting system. Additional features include a carry handle, External D-Rings and stay-put internal stiffeners. The Rocky Mountain Saddle Bags are designed to work effortlessly with Wolf Side Racks. To use these with other racks, choose the "Other Racks" straps. Note that racks must have an oval or rectangle shape (i.e. Hepco & Becker, Touratech, GIVI, Happy-Trail) and the height of the hoop (top to bottom) must not be greater than 9.5 inches. See "Other Rack" video or instruction sheets. This product is made in the U.S. and has a lifetime warranty.
