VaporAiress 4.0 8 Liter Women's Hydration Pack

The 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 exposed front 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 STORAGEFour expandable front mesh pockets (flask-ready with elastic cords) and an interior zip pocket secure essentials, while side pockets, a rear bladder-compatible compartment, and an external bungee provide additional storage. 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).
