Topeak’s Wedge Pack II features a unique, positive locking mount that makes attaching and removing the pack a snap. A rain cover is included, if you get caught in a storm; just cover the pack and your belongings will stay dry. It’s expandable, so you’ll have plenty of room for carrying tubes, a C02 pump, wallet, keys and whatever else you need. For low-light conditions, a 3M reflective stripe adds safety and its 1000-denier, Teflon-coated construction makes the Wedge Pack durable and tough.
