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.

The Detachable Dual Holster Hydration Waist Pack is the perfect solution for simple, on-the-go hydration.

As outdoor enthusiasts, we know a thing or two about Trail running, hiking in 115 degree heat, and the importance of hydration!  

We also know there’s nothing better than taking a big swig of cold water, hours after its poured. Those who sweat hard, hydrate harder, and demand replenishment, need reliable hydration at all times. Your liquids will stay cool twice as long, thanks to the Tri-Layer™ insulation and radiant heat reflective technology. The compact and durable design fits our Detachable Hydration Waist Pack and includes a high-flow, self-sealing Surge Cap™ for spill-proof hydrating. Enjoy your hot or cold liquids with thermal insulated bottle design. Comes in two sizes 20 & 24oz.

 The Breakaway Surge valve maximizes flow rate and self-seals to eliminate spills and splatter. It’s spill-proof when open, and pushes closed for leak-proof transport.

 100% BPA-free insulated water bottle. Updated design features triple wall insulation, keeping your liquid cooler 2X longer.

 The innovative Surge Cap is two pieces–cap and valve–and easy to clean. Simply twist, pull, and wash. Plus, they’re dishwasher safe.
