The Osprey Raven LT 12 L Hydration Pack is a women's-specific bike pack for staying hydrated while riding. Carry water and everything else you need for day-long rides with this spacious pack. The main interior offers internal organization for bike tools and keys, plus space for layers and food. An external zipper at the backpanel makes it easy to load and unload the included Hydraulics 2.5 L reservoir, while harness routing and magnetic bite valve attachment keep the hose in place. Ride like the wind, and this pack will stay put with the help of a winged shoulder harness, AirScape backpanel, and airmesh wrap hipbelt.
