Whether you're mounting up for a cross country loop or crushing downhill runs at the resort, shoulder the Osprey Women's Raven 10 Hydration Pack for an unrivaled fit and easy thirst quenching. The three-liter Hydraulics Reservoir is shaped to match the profile of the back panel for improved balance and less sloshing, while the magnetic bite valve keeps the hose from whipping around when you fly down steep straightaways. Although fairly compact, the Raven has plenty of room for a light layer, a substantial snack, and all the tools you need to get your bike back to the trailhead after a mid-ride breakdown.
