Osprey Duro 15 Backpack With Flasks

Push your stride to its limits with the Duro 15, built for inspired long-distance trail running, training and racing where support stations are few and far between.

The Duro 15 pack was designed with runners in mind for those who push themselves to the very limit of trail endurance. Osprey has exceptional attention to detail, and the Duro 15 shows this, firstly with the lining of the pack which is contact mesh, to keep it comfortable and breathable, even when you're under intense pressure. The mesh allows air to circulate, providing you with cooling sensations as you move. The bag also has multiple stretched mesh and zippered pockets on the front of the vest combined with integrated hip belts, allowing you to store essentials with easy access to these items. There are also upper vest pockets that contain two 500ml soft flasks with extension hoses that can be swapped in and out, providing you with on-the-go hydration. The compression straps included ensure that the pack is close-fitting, whilst large stretch mesh pockets are large enough to store items such as a waterproof jacket, or even a hat and gloves. On the rear of each shoulder strap features a 'Stow-on-the-Go' loop which can comfortably and efficiently carry trail running poles and keep them out of the way, whilst also keeping your hands free. The Duro 15 also has sternum straps which are both removable and adjustable, done with a single-hand release, as well as are elasticated so they don't inhibit your movements. The straps help to balance the pack and keep it close and stable, making it feel lighter so you can go further for longer. Finally, the Duro 15 is also compatible with Hydraulics reservoirs.
