Nathan Hydration vest VaporAiress 4 8L

BUILT FOR LONG MILESThe VaporAiress was inspired by trail runners who spend hours on the move-where comfort, stability, and adaptability matter more with every mile. As conditions change, gear shifts, and layers come on or off, this vest is designed to adjust with you, not against you. Available in a unisex fit and a women's-specific design, each version is engineered to contour the body for a secure, comfortable carry over long distances. ON-THE-RUN ADJUSTABILITYA women's-contoured interior wrap panel with exposedfront toggles lets you micro-adjust fit mid-run for a secure, no-bounce feel. BREATHABLE + FAST-DRYING3D mesh maximizes airflow while durable ripstop dries quickly to keep you cool and comfortable on long runs. INTUITIVE STORAGEMultiple front-access pockets, pole keepers, and compatibility with both flasks and a 2L bladder adapt as your run evolves. HYDRATE WITH EASEIncludes a 2L Nathan x HydraPak bladder with a quick-release hose for easy cleaning. Front flask pockets holds up to two 20oz / 591ml soft flask (sold separately).
