Osprey Duro

Yes, the Duro includes a run-specific 1.5-liter hydration reservoir, so you are ready to hit the trails right out of the box.

Unlike a traditional backpack, the Duro is designed as a vest with a 3D Spacermesh bodywrap. This creates a snug, bounce-free fit that moves with your body, preventing the shifting or chafing often experienced with standard packs.

Yes, the vest features dedicated attachment points specifically designed for trekking poles, allowing you to stow them securely when you don't need them.

The Duro uses a ventilated backpanel and padded mesh straps to maximize airflow. While no vest is completely sweat-proof, these materials are engineered to keep you as cool and comfortable as possible during high-exertion activities.

The Duro comes in Small, Medium, and Large sizes, which differ slightly in dimensions and weight to accommodate different torso lengths. We recommend measuring your chest circumference and torso length to match against the sizing chart, as a proper fit is essential for preventing bounce.

With a 6-liter volume, the Duro is designed for endurance runs. It has ample smart pocketing for gels, nutrition, and a light windbreaker, though it is not intended for carrying heavy overnight camping gear.
