Ruffwear Swamp Cooler Zip Cooling Dog Vest

The Swamp Cooler Zip efficiently cools dogs during light and fast, high-intensity adventures through shading and evaporative cooling. The light and sleek Swamp Cooler Zip uses shade-providing spandex over the back and Ruffwear’s Swamp Cooler™ tech in the chest panel for an evaporative cooling effect that disperses heat from the dog’s core. To tap into the Swamp Cooler™ tech, soak in water, zip on your dog, and go.

What's New: We updated the Swamp Cooler Zip (formerly known as the Jet Stream) with new materials to hold more water and a longer charge, and new patterning and construction for an improved fit and performance.
