Osprey Duro 6 Running Hydration Pack

Osprey Duro 6 Running Hydration Pack is the dedicated trail-running hydration vest from Osprey’s running-pack lineup, sized for half-marathon to ultramarathon distances where the racer needs water, gels, and emergency layers in a vest that disappears on the body.

This is the vest trail runners, ultra runners, and fastpackers reach for because Osprey running-vest fit is the brand benchmark, and 6-liter capacity is the working ultra-distance window. Reservoir compatibility ships standard.

Why trail runners pick the Duro 6

• 6-liter ultramarathon capacity.
• Running-vest fit that disappears on the body.
• Reservoir compatibility for hydration.
• Osprey All Mighty Guarantee lifetime coverage.

For trail runners and ultra racers, this is the Pack Osprey built for running.
