Topeak MondoPack Hydro (w/Fixer)

Topeak's MondoPack Hydro features a unique, positive locking mount that makes attaching and removing the pack a snap. Its streamlined design prevents thigh rub, even when fully loaded and the large main compartment offers plenty of room for carrying tubes, a C02 pump, wallet, keys and whatever else you need. For low-light conditions, 3M reflective strips on three sides add safety and its 1200-denier construction makes the MondoPack durable and tough. And, the rear water bottle pocket lets you bring an extra bottle along for the ride.
