Made to haul all the gear you need—but flexible enough to slim down for shorter rides—the Osprey Raptor 14 Hydration Pack is their premium pack for mountain bikers who demand top quality from their gear. Don't like how hydration packs feel over gnarly terrain? Neither did Osprey. So they designed shoulder straps in the shape of wings that curve the same way you do when youÕre in riding position. An AirScape suspension and backpanel provide a close-to-body carrying experience and elevate comfort and stability to unprecedented levels, while still allowing for dynamic body movement. An included 2.5-liter reservoir with direct-zip hose access ensures straightforward loading, while a tool roll organizes the ingredients to get you moving again should you have any trailside troubles. Standard helmets attach with the LidLock system and side compression straps will fit your full face helmet.
