The Osprey Hydraulics LS 1.5 L Water Reservoir is a low-profile reservoir built for run and bike adventures — compatible with the brand's Duro™/Dyna™ and Escapist™ Velocity vestpacks. It's the do-anything hydration reservoir designed to keep fast-moving athletes drinking on the go.
A shortened hose length and a compact bite valve that opens and closes with a thumb make it easy to sip mid-stride or mid-ride without breaking rhythm, and the low-profile 1.5-liter shape sits flat and stable in a running or biking vest. The design fills, loads, and drinks with minimal fuss, so hydration keeps up with your pace. Low-profile, easy-sipping, and run/bike-ready, it's the reach-for-it reservoir that fits your vestpack and your fast-moving days.
