Scorching days on the trail, pedaling through the dry summer heat, or trail running in the blazing sun can quickly turn a fun outdoor adventure into a miserable, even dangerous situation. Staying hydrated is critical, but you have to stay cool, too. The ExtremeMist Misting and Drinking Hydration Backpack is the only pack on the market that does both. 

With a drinking tube and misting system, you can hydrate on the go while enjoying a cool, energizing mist. An insulated reservoir cover keeps your drinking water refreshingly cold, and mesh pockets on the pack store your outdoor essentials. With easy-to-use drinking, misting, and storage systems, this pack can transform a sweltering day on the trail into a pleasant outdoor adventure.

The new and improved Personal Cooling System (PCS) with higher PSI and a water-cooled pump comes with a rechargeable battery and an 8-speed wireless remote for adjusting misting settings. 

The PCS cooling pump comes easily out of the backpack. It’s also compatible with our Quad Hose/Nozzle Kit for large-scale cooling. 

The Misting and Drinking Hydration Backpack comes with the Personal Cooling System (PCS) fully installed.
