Streamlined stability and hydration on the move with the Duro 1.5L Hydration Backpack
What Our Gearhead® Experts Are Saying:
"The Duro 1.5 is my go-to for fast, lightweight runs. It stays secure with zero bounce, even when fully loaded, and the dual flasks make hydration easy to manage. The fit feels dialed in—almost like part of my running kit, not extra gear."
Engineered for distance and designed for comfort, the Duro 1.5L Hydration Backpack delivers hydration and stability for every mile. Its minimalist profile includes two 500 mL flasks for balanced hydration on the move, while the flexible stretch mesh construction adapts to your stride for a secure, bounce-free fit. Thoughtful front and rear storage keeps essentials within reach, from gels and gloves to a packable layer.
Constructed with soft, breathable mesh and repatterned flask pockets for improved access, the Duro 1.5 keeps you cool, supported, and distraction-free from start to finish. Compatible with the Hydraulics LT 1.5L reservoir (sold separately), it’s ready for everything from tempo runs to ultramarathons. Made with bluesign-approved, recycled materials, this vest combines technical precision with a sustainable touch.
