Hydraulics LS 1.5L Water Reservoir

The Osprey Hydraulics LS 1.5L Reservoir is built specifically for fast movers - not a smaller version of a hiking bladder, but a different design for a different motion. A shortened hose and compact bite valve reduce dangling length and bulk against the chest, while a magnetic hose attachment keeps the valve clipped to the sternum strap and within reach without breaking stride.

• Low-profile design for run/bike vestpacks — sized and shaped specifically to sit flat against the back in Osprey's running and biking vest packs, avoiding the bulk and shifting that a standard hiking reservoir creates in a close-fitting vest.
• Shortened hose length — reduces excess hose hanging and swinging during running or biking motion, keeping the line tidy and out of the way.
• Compact bite valve with thumb-operated on/off lever — opens and closes with a single thumb motion, allowing one-handed operation without breaking cadence or removing a hand from a handlebar for longer than a moment.
• Magnetic hose attachment — clips the bite valve securely to the sternum strap for instant access, and holds firmly enough to stay attached through the motion of running or rough trail riding.
• Slide-Seal opening — a compact sliding closure that allows one-handed filling, removes the bulk of a traditional screw-top or fold-over closure, and slides into the reservoir sleeve of a pack easily.
• 1.5L capacity at 120g — sized for the duration of most running and biking sessions without adding meaningful weight to a vest pack.
