Description Double-Wall Construction with Open-Cell Foam Technology
Cool off after a tiresome adventure with water you can trust. The Hydrapak UltraFlask IT is 500-milliliters of clean and pure water that features all-new IsoBound™ insulation technology to keep water cold and reduce sweat in warm temperatures. Engineered to keep fluids at an ideal temperature 38% longer than a standard flask. After all, cold water is much more refreshing.
IsoBound™ insulation prevents heat transfer from the user to the hydration, so it is the ideal solution for a wide range of outdoor endurance activities. The four-layer design provides more structure and an enhanced grip for the ultimate comfortable carrying experience. The high-quality multi-cap includes a bite valve and an adjustable drink tube so you can refill on your water however you prefer.
Go the distance with the Hydrapak UltraFlask IT to cool you down. A double-wall construction utilizes open cell foam technology to create a barrier, slowing the heat transfer that usually results in sweat on the outside of the bottle. With a vest-pack fit and bounce-free stability, you can sit back and relax with trustworthy hydration for your next adventure.
