HydraPak Velocity IT Reservoir

IsoBound technology uses a multi-layer construction that creates a thermal barrier between your body heat and the liquid inside. This significantly slows down heat transfer, keeping your fluids at a refreshing temperature much longer than a standard, non-insulated reservoir.

The Velocity IT is designed with a soft, compressible material that makes it highly adaptable. Because it lacks a rigid frame, it easily conforms to the shape of most standard hydration vest pockets, though you should double-check your vest's pocket dimensions to ensure a 1.5-liter capacity fits comfortably.

Not at all. The reservoir is designed for easy maintenance, and the wide opening allows you to reach inside to scrub it out. We recommend rinsing it thoroughly with warm, soapy water after each use and letting it dry completely to prevent any residue buildup.

Yes, the closure is engineered specifically for high-movement activities. It features a secure, leak-proof seal that is designed to withstand the jostling and pressure of trail running, so you don't have to worry about spills inside your pack.

The Velocity IT weighs 5.75 ounces. While the insulation adds a slight amount of weight compared to a non-insulated bladder, the trade-off is minimal for the benefit of having cool water throughout your entire run.
