More miles, less stopping — the Hydraulics 3L Reservoir makes it happen

What Our Gearhead® Experts Are Saying:


"The QuickConnect hose system is a genuine upgrade — I can swap in a filter or top off mid-hike without wrestling with the bladder, and the magnetic clip keeps the bite valve exactly where I want it on the strap. It integrates seamlessly with my Osprey pack and holds enough water for a full day out."


Staying hydrated on the trail shouldn't require stopping. The Osprey Hydraulics 3L Reservoir keeps water moving with a Hydrapak Blaster bite valve, a magnetic hose clip that holds the tube in place on the shoulder strap, and an on/off switch that prevents drips when you don't need them. The Slide-Seal top fills quickly and closes securely, and a Hydrostatic Backerplate gives the bladder enough structure to slide cleanly into any Osprey sleeve.


The QuickConnect system lets you detach the hose and attach a water filter in the backcountry without draining the reservoir first — a small detail that pays dividends on longer, more remote trips. Clean, capable, and purpose-built for Osprey packs, the Hydraulics 3L handles hydration so you can focus on the miles.
