Equipped with a Hydraulics LT 1.5 Reservoir and a number of aerobic-minded features, the streamlined Osprey Duro 1.5 vest pack is specifically designed for trail running.
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. The AirMesh materials used on the backpanel enhance breathability and provide next-to-skin comfort. Other trail-friendly features include a zippered stash pocket on the harness, front harness stretch mesh pockets, and a zipper pull that doubles as a safety whistle.
A dedicated compartment houses the included 1.5 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.
The Osprey Duro 1.5 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”.
