Keep your water cold for as long as possible on long trail runs and other outdoor endurance activities with the Hydrapak® Velocity IT 50-oz. Insulated Hydration Reservoir and Drink Tube. Made with IsoBound™ insulation technology, this 50-oz. reservoir combines double-wall construction and open-cell foam technology to slow heat transfer from the user to the fluid inside the reservoir. 100% BPA- and PVC-free, this durable TPU reservoir features RF welded seams for long-lasting durability and elasticity and can even be frozen. A sweatproof, 4-layer design, this high performance reservoir features a lightweight grab tab for easy handling in and out of packs for easier refills. The reservoir's Unifit hanger is built to work with clips, hooks, and loops in many popular hydration packs and backpacks, including Salomon, Nathan, Osprey and CamelBak. High-flow design comes with a flexible and insulated Hydrafusion drink tube and high-flow, self-sealing Comet bite valve designed for 1-handed use. Made with the Plug-N-Play™ connect system, the Velocity IT allows users to easily disconnect the drink tube without worry thanks to its auto shutoff valve to remove the reservoir for refills. Easy-to-use Slide-Seal™ top opens wide for quick filling and closes tight. Internal drying tab makes it easy to turn the reservoir inside out for deep cleaning and drying.
