Osprey Duro Dyna Hydration Waist Pack with Hydraulics Soft Flasks — Seaweed Green / Limon

Meet the Osprey Duro Dyna Hydration Waist Pack, a lightweight belt built to move with you on every trail and city run. Designed for a close-to-body feel, it keeps hydration and essentials within easy reach, so you can focus on cadence, scenery, and pace. A total of 720 mL of hydration comes from two Hydraulics 360 mL Soft Flasks, letting you sip on the go without breaking rhythm. The belt is crafted from bluesign approved 100% recycled nylon stretch mesh, pairing performance with a more sustainable touch.

Designed for movement and minimal distraction

The Duro Dyna hugs the hip with a bounce-free profile, helping you maintain form and stride whether you’re chasing a personal best or exploring a new route. Smart pocketing keeps your essentials—hydration, gels, a phone, and a whistle—within arm’s reach, so you can stay focused on the ground ahead rather than hunting for items.

• Close-to-body fit reduces bounce and bulk for more confident movement
• Accessible pockets deliver quick access to hydration, gels, phone, and emergency whistle
• Reflective graphics improve visibility for early-morning or low-light runs
• Hydration included: two 360 mL soft flasks keep sipping options flexible
• External loops accommodate trekking poles or wet clothing as needed
• Compact dimensions and light weight support extended sessions without fatigue

Materials that matter

Crafted with bluesign approved 100% recycled nylon stretch mesh, the Duro Dyna blends durability, stretch, and a lower environmental footprint. The fabric is designed to breathe with you, helping comfort stay high as you push cadence on longer outings.

Versatility for everyday adventures

New colorways offer style options beyond the baseline. The belt’s two-flask hydration setup suits everything from a quick park loop to a longer endurance theme, while the included capacity leaves room for small items like keys, gels, and a phone. If your route calls for a little extra gear, the external loops provide a flexible pathway for trekking poles or a compact extra layer.
