Topeak's Survival Tool 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. Plus the included 17-piece toolkit has everything you'll need to fix your bike on the go. 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.
