An insulated version of Hydrapak's lightweight Velocity 1.5L reservoir, the Velocity IT 1.5L features new IsoBound technology. Engineered to keep fluids at an ideal temperature 38% longer than a standard reservoir. The four-layer design provides users with more stability, an enhanced grip, and a no-sweat, comfortable carrying experience without sacrificing the simplicity. Preventing heat transfer from the user to the hydration, it is the ideal solution for a wide range of outdoor endurance activities.

• IsoBound Technology keeps water at an ideal temperature 38% longer. The double-wall construction and open cell foam technology create a barrier – slowing the heat transfer from the user to the hydration.
