Osprey Hydraulics LS 1,5L rezervoar

Trail runners and fastpackers who need hydration without the bounce will appreciate the Osprey Hydraulics LS 1.5L Reservoir. Designed for lumbar-specific packs, it sits low and stable, keeping your center of gravity balanced on technical terrain. The magnetic bite valve clips securely to the sternum strap, so you can grab a drink without breaking stride.
