The perfect saturday singletrack companion, the Osprey Sylva 12L Backpack goes right from the gear closet to the trailhead with everything you might need for a full day in the saddle. Thanks to the AirSpeed suspension system and BioStretch shoulder harness, the Sylva is streamlined and comfortable on the back while being highly functional and supportive at the same time. An included Hydraulics 2. 5L reservoir ensures that water is never far from reach, while the integrated high-visibility raincover keeps your pack and gear dry on your ride from start to finish. It also features a simple helmet carrier to free up internal space, as well as a multitude of zippered pockets, inside and out, to keep all of your tools, tubes, snacks, maps, and tunes organized.
