Whether you're biking the White Rim or exploring Chaco Canyon, Osprey's Raptor 10 Hydration Pack will carry everything you need to stay prepared, hydrated, and comfortable while you're out on the trail. Made with Osprey's supportive Atilon foam framesheet and the breathable Airscape back panel, the Raptor easily carries a day's worth of gear and three liters of water in the included Hydraulics reservoir. In terms of features, the Raptor comes with a Lidlock helmet attachment point, a front stash pocket for quick access to spare tubes and trail maps, and a stretch mesh pocket that conveniently stows anything from an extra layer to that little stuffed pink elephant that you just can't seem to leave out of your adventures.
