The Hydrapak Velocity IT 1.5L is the perfect hydration solution for mountain running, mountaineering, and backpacking in the Eastern Sierra. Featuring our innovative IsoBound™ insulation technology, this hydration pack keeps water cold and sweat-free in warm temperatures. With the ability to keep fluids at an ideal temperature 38% longer than a standard reservoir, you'll enjoy cold, refreshing water on all your adventures.

This BPA-free and PVC-free reservoir is dishwasher safe and easy to clean. It's also leakproof, freezable, and ergonomically designed to fit most standard hydration vests. The four-layer design provides more structure, an enhanced grip, and a no-sweat, comfortable carrying experience.

With an updated high-performance design, this hydration pack provides 20% more flow for easy drinking on the go. The patented Slide-Seal™ top opens wide for quick filling and closes tight for a leakproof seal, and includes a tether to prevent misplacing. The Dual FlexGrip™ handles make the reservoir convenient to carry and access in your pack, providing a secure grip while filling and pouring.

The flexible 36" HydraFlex drink tube is non-kinking and provides a steady flow, and the high-flow Blaster™ bite valve self-seals after each sip and features a smooth twist on/off bar to prevent leaks when not in use. The Plug-N-Play™ connect system lets you easily disconnect the drink tube, and an auto shutoff valve prevents leaking while removing the reservoir from your pack for convenient refilling.

Made of ultra-durable, abrasion-resistant TPU and RF welded seams, this hydration pack is built to last. It has a wide working temperature range and can be frozen (max temp 60°C/140°F). With a capacity of 1.5 L / 50 fl oz and dimensions of 335 x 150 mm / 13.1 x 5.9 in, the Hydrapak Velocity IT 1.5L is the perfect hydration solution for all your outdoor activities in the Eastern Sierra.
