Built to last with sturdy 18oz waxed twill, 10.10oz waxed canvas, premium vegetable tanned leather, and fully lined with 10oz vinyl to keep your gear dry and safe, which is particularly important on a motorcycle. This bag is perfect for all kinds of travel. The zippered flap features a mesh pocket and is shielded from any foul weather by a huge storm flap. A large pocket between the storm flap and the main compartment is a great place to keep wet or dirty gear from contaminating everything else. You can also access the inside of the storm flap from both sides for safe and simple storage of maps, gloves, etc. Finally each bag comes with a leather shoulder strap and four adjustable nylon loop straps for the attachment to the luggage rack or fender struts.
