Cooper gives you three different bags from one basic body: messenger bag, backpack, and satchel. These highly durable bags can be made in a range of sturdy fabrics such as duck canvas, waxed canvas, twill, and heavy ticking.
All versions are lined and feature eight large pockets, magnetic closures, and hardware details. The messenger bag (version 1) has an adjustable cross-body strap. The backpack (version 2) has two shoulder straps and a hang loop. The two-handled satchel (version 3) does double duty as a bike pannier.
