The ExtremeMist Personal Cooling System for Misting and Drinking is great for any outdoor activity. Whether you like long-distance running, cycling, or hiking, the ExtremeMist will keep you hydrated. All you have to do is put the ExtremeMist PCS in a hydration backpack, and you’re good to go. Or, you can purchase the ExtremeMist vest to wear it in. It’s better than just drinking water because you’re also able to mist it on yourself. As you know, this can really help when the sun’s shining on you. And if you don’t feel like wearing the pack, that’s no problem. You can hang the personal cooling system from a canopy, tent, or somewhere else that you can reach to cool yourself off.
