The Viper has your back.

Whether it's an epic relay race, stiff hiking trail, or challenging cross country ride, trust Osprey's Viper 9 Hydration Pack to satiate your thirst-quenching needs. The ventilated Airscape back panel and perforated Biostretch harness not only keep the pack from shifting around during fast-paced pursuits, but it also maintains comfort even when you break a sweat. Additionally, the three-liter Hydraulics Reservoir is shaped to match the contour of the back panel—which means better balance and less sloshing. And to ensure maximum preparation for bike-related break downs or unexpected detours on your hike, Osprey added a large zippered main compartment (in addition to the hydration sleeve) where food, layers, spare tubes, and tools can be carried while the two front pockets make it easy to stash a light rain jacket or trail map for quick access.
