The perfect blend of smart hydration pack and well-ventilated vest, the EVOC Hydro Pro 3L + 1.5L Bladder is the ideal hydration pack for everything from gravel adventures to enduro races. The extra-light hydration backpack sits safely and comfortably on the back during ambitious descents without covering the jersey pockets. Food and equipment also find their place. The quick-access main compartment accommodates a 1.5-liter hydration bladder as well as smaller items and valuables. Two 150 ml mesh pockets on the shoulder straps ensure energy bars and gels remain within easy reach throughout any ride. Two zippered pocket underneath the mesh pouches let are perfect to stow away mini tools or a mobile phone. The lateral AIRO FLEX sections keep the pack snug, yet comfortable, and prevent any side-to-side movement no matter where the road — or trail — takes you. Due to supply chain issues, compatible parts may be substituted at any time without notice. Weights are based off pre-production products at time of publication. Weights may vary in final production.
