Osprey Hydraulics 3L Reservoir – BPA-Free, Leakproof Hydration with QuickConnect & Slide-Seal

Hydration on the go, reimagined

Meet the Osprey Hydraulics 3L Reservoir, a hydration solution designed for long days on trail, road, or travel. Crafted with BPA-free materials, this extra-large bladder blends practical performance with everyday comfort, so you can focus on your route rather than your setup. It’s built to slot into hydration-ready packs and works with the HydraClip system for quick, clean integration.

Smart design that keeps you moving

The reservoir features a leakproof Slide-Seal opening that opens wide for fast filling and thorough cleaning, then seals securely to help prevent spills. Inside, a rigid backer plate adds structure, making it easier to load into your pack and keep upright during movement. A central baffle creates a slim, low-profile shape that minimizes water slosh as you hike, ride, or backpack.

• Leakproof Slide-Seal opening — one-handed, easy filling and cleaning, with secure closure.
• Rigid backer plate — built-in support to help it slide in and stay upright.
• Slim, slosh-free profile — maintains balance when the bladder is full.
• Magnetic bite valve & hose — high-flow drinking starts with a simple, secure attachment.
• BPA-free, pack-friendly design — compatible with most hydration-ready Osprey packs and HydraClip.
• Item dimensions: 17.3H x 7.5W x 0.4D in; weight: 0.52 lb.

Real-life use, real comfort

On hot days, the high-flow bite valve with a thumb-operated on/off lever lets you hydrate without fumbling, while the magnetic hose keeps the line tucked away when not in use. The 3-liter capacity reduces the need for frequent refills on longer treks, bike rides, or travel days, yet remains pack-friendly enough to prevent bloating your load.

With QuickConnect compatibility and HydraClip integration, you can expect quick, tidy setup with compatible packs, enabling you to focus on your route rather than equipment management. This reservoir is designed for varied adventures—from quick trips to more extended expeditions—offering a practical hydration option without overpromising results.

• Ideal for long hikes and cycling sessions where constant sipping matters.
• Great for backpacking and travel days that benefit from fewer refills.
• Easy to load, stable in-pack performance, and simple to maintain.
