The Ruffwear Swamp Cooler provides protection from the sun and cooling through evaporation. In warm climates, dogs typically stay cool by seeking shade during the heat of the day and moving around in cooler temperatures. The Swamp Cooler allows dogs to perform in hot climates. To activate the Swamp Cooler, soak in water, wring out and place on your dog. The light-colored fabric reflects solar radiation, while evaporative cooling pulls heat from the dog. The integrated leash portal allows leash attachment when the Swamp Cooler is worn over our Front Range™, Hi & Light™ or Web Master™ Harnesses.

My dog loves this

I am so happy with this cooling vest. My dog used to do heavy panting when it was hot outside. Now he goes, does his business and no more panting. This is a must in Texas

Swamp Cooler for the Desert

This item does gets the job done. I live in Phoenix, AZ and have a golden retriever who loves to lay outside and "guard" the house after the sun goes down. It's still super hot out when the sun goes down and the swamp cooler allows him to safely be outside for a bit. It is also great for transporting the dogs during the summer. I highly recommend this product.

This has been a life saver this summer. It’s been over 100 degrees most days, this has helped to cool my dog down. I just soak the swamp cooler and put it into a 2-gallon ziplock bag before going out so it doesn’t wet up my car. Once one I’ve noticed I have to re-wet it a few times and it gets dirty easily but it is also easy to clean. overall a great product.

Best thing ever for senior dog

Daytime temperatures were slated to get into the high 90's/low 100's during an unplugged August camping trip this year. For humans and the single-coated younger dogs, an afternoon in the creek would solve any problem of overheating but my senior Akita mix takes forever to dry which doesn't make for a great night sharing a tent. The Swamp Cooler was a miracle worker! As soon as the temps started climbing and he started getting uncomfortable, on went the Swamp Cooler. Most days, he went from panting to napping and snoozed away the worst of the heat without noticing! Yet another amazing product from Ruffwear - thank you!
