Osprey Duro Running Vest

The Duro is specifically engineered to prevent bounce. It features a slim, ergonomic profile that sits close to your body, and the ErgoPull hipbelt allows you to cinch the pack down securely so it moves with you rather than against you.

Yes. The vest is designed with multiple harness pockets located on the front, allowing you to grab gels, snacks, or your phone without needing to take the pack off or slow down.

The included 2.5-liter reservoir is designed for quick access and consistent flow. While it is durable, like all hydration bladders, it requires regular rinsing and drying to keep it fresh between long runs.

With a 15-liter capacity, the Duro is well-suited for ultra-marathons and long-distance trail running. It provides enough room for essential gear, extra layers, and hydration, making it a reliable choice for endurance efforts.

Unlike a standard hiking pack that sits on your back, the Duro fits like a vest. The padded mesh straps and harness system distribute weight across your chest and torso, which is essential for maintaining stability and comfort during high-intensity movement.

The pack is water-resistant, which helps protect your gear from light rain and trail spray. However, it is not fully waterproof, so if you are running in heavy downpours, it is best to put sensitive electronics or extra clothes in a dry bag inside the pack.
