Osprey Duro Pro 10 Running Vest 10L Mystery White Size S

Long-distance trail runners often struggle with carrying enough water and gear without bulky packs that bounce and chafe. The Osprey Duro Pro 10 solves this by offering a vest-style fit that hugs your torso, keeping essentials secure and accessible while you move fast over technical terrain.

Who is it for

Built for ultra runners, fastpackers, and anyone tackling long miles in the mountains. Its unisex design and size S fit smaller frames, providing a stable, no-bounce carry for hydration, nutrition, and layers.

Main features

• 10-litre total capacity with a main zippered compartment and rear stretch pocket for quick access to layers or a rain shell.
• Includes two 500ml Osprey Hydraulics™ soft flasks that sit in front harness pockets, so you can sip without breaking stride.
• Multiple front harness pockets—zippered and stretch—keep phone, gels, and salt tabs organised and reachable.
• Dual adjustable sternum straps with buckle closure let you fine-tune the fit for comfort and stability on any terrain.
• Stow-on-the-Go™ trekking pole attachment allows you to stash poles without removing the vest.
• Contact Mesh backpanel enhances breathability and reduces sweat build-up during high-output efforts.
• Reflective details and an integrated safety whistle boost visibility and security in low-light conditions.
• Compatible with a 1.5L hydration reservoir (sold separately) for longer unsupported stretches.
• Made from 320D nylon stretch ripstop for durability that withstands brush and rock scrapes.
• YKK zippers throughout ensure reliable operation even when you are wearing gloves.

Tips

For the best fit, adjust the sternum straps so the vest sits snugly without restricting breathing. When using the soft flasks, squeeze out excess air before closing to reduce sloshing. The rear stretch pocket is ideal for a lightweight windbreaker or extra gloves—items you might need quickly as weather changes.
