VaporAir 3.0 7L Hydration Pack

For half-day efforts and long training runs where you can't afford to slow down, the VaporAir 3.0 is our go-to hydration pack for serious trail runners and ultra-distance athletes. Its body-mapped, ventilated back panel pulls heat away from your back — a real difference-maker in Southern summer humidity. High-visibility Safety Yellow accents handle low-light visibility without a separate vest.

• 7-liter total capacity carries nutrition, layers, and gear for half-day runs or extended training efforts
• Ventilated, body-mapped back panel promotes airflow to cut heat and sweat buildup — critical when temps and humidity climb
• Close, bounce-free fit moves with you on technical terrain instead of shifting and throwing off your stride
• Available in three size ranges — XS-M, L-XXL, and extended 1X-3X — so athletes of all builds get a dialed fit
• Deep Blue colorway with Safety Yellow accents improves visibility on early-morning and low-light runs without extra gear
