When shade is low and the mercury is high, dogs can count on the Swamp Cooler to help get them outside. Strategic material choices and design offer solutions for the challenges that warm-weather exploring presents. The light-colored fabric reflects solar radiation and provides shading while wetting the vest activates our Swamp Cooler™ Tech for that refreshing, just-stepped-out-of-a-lake feeling also known as evaporative cooling. Just give it a soak, put it on your dog, and go. When it dries, re-soak it to recharge it.

The Swamp Cooler Vest includes side-release buckles for easy on/off and a leash portal so it can be worn over a harness – topping off the essential features to make it our highest-coverage cooling option in the Swamp Cooler™ Collection.
