Designed for distance runners and endurance athletes, the Osprey Duro 15 offers a stable, body-hugging fit with ample room for hydration, nutrition, and essential gear. Its Backpanel 3D Spacermesh bodywrap and supportive foam backpanel with extended hipwings provide breathable comfort and stability, while the Harness Airmesh bodywrap and padded mesh straps ensure a secure, ventilated fit. With a quick-adjust Ergopull hipbelt, the vest adapts quickly to changing loads and terrain.

Storage is intelligently distributed with two extra-large stretch mesh flask/food harness pockets, four lower stretch mesh food/supplement pockets, and a vertical zippered harness slash pocket for valuables. The vest includes two 500mL soft flasks and a hydration sleeve with direct-zip access and hose routing for optional reservoir use. Additional space comes from the large front zippered compartment, stretch mesh front pocket, and two extra-large zippered lower hip pockets, complemented by two open stretch mesh hip pockets for quick-grab items.

Customisable and trail-ready, the vest includes dual snap-in adjustable/removable chest straps, trekking pole/ice axe attachment, and a tuckaway safety whistle, all made with recycled materials and treated with Perfluorinated Chemicals (PFC) free and Per- and Polyfluoroalkyl Substances (PFAS) free DWR finish.
