Made from rugged and durable nylon, this bag makes any load easy to carry with its ergonomically designed padded shoulder straps. When you wish to carry it as a messenger bag (versus a backpack), just tuck away the shoulder straps and it converts to a messenger bag. The bag features a large rear compartment, dual access front component and three convenient front zip compartments. There’s even an insulated bottle holder located at arm’s reach. Retails for $59.99.
