All-day comfort and hydration with the Duro 6L Hydration Backpack

What Our Gearhead® Experts Are Saying:


“The Duro 6L is my choice for long training runs and races where I need more storage but still want that close, bounce-free fit. The pockets are smartly placed, the mesh feels super breathable, and the included flasks keep me fueled without breaking rhythm.”


The Duro 6L Hydration Backpack is built for runners who go long—delivering stable hydration, balanced storage, and lasting comfort for endurance pursuits. With a refined fit that hugs the body for smooth movement, this vest eliminates bounce and hotspots while keeping essentials within easy reach.


Two 500 mL flasks provide quick hydration on the move, and streamlined pocketing stores extra layers, gels, and nutrition. A rear compartment accommodates the Hydraulics LT 1.5L reservoir (sold separately), giving you flexible hydration options for big days on the trail. The lightweight, 360° stretch mesh construction enhances airflow and mobility, keeping you cool and focused from start to finish.


Made from bluesign-approved, recycled nylon and spandex with a breathable airmesh contact fabric, the Duro 6 combines performance comfort with sustainable design. For runners chasing distance, consistency, and confidence, it’s the pack that keeps up with every step.
