For travelers on style, this backpack is design to be use in two different ways through its ingenious shoulder strap configuration. The shoulder strap is joined in the center by a durable zipper. Simply open the zipper to split strap for a backpack set-up. For a cross body setup, close the zipper and put hooks on preferred wear side. The body is made from discarded truck inner tube lined with waterproof fabric and features multiple internal pockets and a keyhook. Zipped external pocket in front and big mesh pocket at the back provides easy access extra spaces. Large enough for a long “3-Day” out of town trips.
