The women's specific raven 10 will join you on a bike ride anytime. The single track may be rugged but your pack will carry close thanks to osprey's bio stretch harness and hip belt that comfortably connect the pack to your body. Specially designed baffles in the 3 liter hydraulics reservoir reduce liquid movement for increased pack stability at high speed. The hydration sleeve is zippered for convenient refills and the hose routes over the right shoulder strap to the sternum strap where it anchors with a magnetic disk for on-the-fly access to the bite valve. The main compartment is accessible via a front zipper panel. There's a stretch mesh front pocket for stashing a layer at the bottom of the big climb, zippered hip belt pockets to keep a phone or other valuables secure, and a special scratch-free sunglass pocket to protect your shades. The lid lock helmet carry system gives you a place to secure your helmet when you're off the bike. If you have mechanical troubles on the trail, a roll out tool pouch provides organized access for Rapid trailside repairs. And if you ride late, there's a blinker light attachment point and reflective patches for nighttime visibility.
