Equipped with a Hydraulics LT 2.5 Reservoir, gear-storing capacity, and a number of easy-access organizational features, the Osprey Duro 15 hydration vest pack is designed for long ultra races or unsupported backcountry running adventures.
Featuring comfortable, breathable mesh, the pack’s harness is designed to mirror the contours of your body, offering a fit that feels more natural than that of many traditional backpacks. Dual chest strap buckles stabilize fit and offer a broad range of adjustability. A unique tabbed design allows you to disconnect the straps from either side of the harness or remove them entirely. A padded hipbelt with a user-friendly ErgoPull closure further stabilizes weight and allows you to carry all the gear you need for a long day on the trail. The AirMesh materials used on the backpanel and hipbelt enhance breathability and provide next-to-skin comfort. Compression straps help to keep your entire load balanced and stabilized.
The main compartment of the Duro 15 has dual zippered access points. There is a front panel compression pocket and a smaller zippered front stash pocket. A dedicated compartment houses the included 2.5 liter hydration system and a zippered entry allows hassle-free access. A QuickConnect feature on the detachable drinking tube allows for faster refills and a magnetic bite valve provides a high flow rate and connects efficiently to a magnet on the front of the harness when not in use. The reservoir’s wide mouth is easily accessed by a large, quick-seal cap that further adds speed and efficiency to refills. An anti-microbial treatment fights bacteria build-up inside the BPA and PVC-free reservoir and keeps water tasting fresh and clean.
Other trail-friendly features include a zippered stash pocket on the harness with a zipper pull that doubles as a safety whistle, deep and over-sized stretch mesh harness pockets that are ideal for flasks or phones, two additional, smaller stretch mesh harness pockets, and zippered hipbelt pockets.
The Osprey Duro 15 hydration vest pack is available in your choice of color and size options. Sizing is based on the circumference of your chest, measured at the widest part of the chest slightly below your armpits. The Small/Medium size best fits chests measuring 34”-40” and the Medium/Large best fits from 39”-45”.
