Duro 6 is a versatile running vest designed for long days on the trails, offering smart pocket placement, a stable no-bounce fit and hydration included straight in the pack. The lightweight, soft and packable construction made from 360° stretch structured mesh ensures the vest stays exactly where it should, even on multi-hour runs.
The vest includes two Hydraulics™ 500 ml soft flasks with removable WingStay™ stabilisers, so fluids and calories are always within reach. A well-thought-out pocket layout and compatibility with a Hydraulics 1.5 L reservoir (not included) make the Duro 6 a reliable partner for any trail challenge.

A back panel covered in 360° stretch mesh distributes the load evenly across the body, while the front flask pockets with special patterning and dual anchoring, together with dual sternum straps, eliminate unwanted vest movement even during dynamic running. - Organised storage for trail essentials
Six stretch mesh pockets for food and accessories, a front vertical-zip pocket with a safety whistle, two zippered rear compartments, a Shove-it pocket with buckle closure and a front trekking pole carry system ensure everything you need is quick and easy to access on the move.
