The ExtremeMist™ Personal Cooling System (PCS) keeps you cool in the hottest places. It's one of the best ways to keep you cool while hiking, running & cycling. The ExtremeMist retrofit kit can transform almost any
hydration backpack; it allows you to "drink & mist" from the same
reservoir! Or purchase our ExtremeMist™ vest/pack with the personal cooling system (PCS) already
installed. "Just Add Water!" The PCS is also useful out of the pack, on
tents, canopies, umbrellas, beach chairs, boats, ATVs and anywhere else
you want to cool down.
