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.

The Swamp Coolest

So far we have only tested it out in the heat a few times but I already think this will be a go to for my pup Ford all summer long! Being an almost all black dog my baby bean is very susceptible to temperatures over 82 but also loves to be outside all day! With this I’ve already seen a difference in how much he needs to hide in the shade and it takes much longer for him to get to that point where we have to hide inside! You can really see the quality in this product too!

Works amazingly

We have a 125 lbs 2 year old mastiff, he is a dark brindle and with this jacket his body stays cool. Also an even better result is the drool production is down 50% I love ruffwear products from balls to frisbees to this jacket, it is the only product that has withstood the punishment a big dog can give, keep it up Ruffwear, don’t ever change your quality

It's good for outdoor use but you can't really use it inside

This is good for outdoor use but I bought it for my service dog to wear during the summer and we can't use it because we frequently go in and out of buildings and even if you wring it out very well you still drip water everywhere which is unacceptable for any kind of public access work so we might be able to use this for an outdoor festival one day but it is pretty useless for our day to day activities

Swamp Cooler

It clearly helps, reflection and evaporative cooling. One has to be aware of how fast the coat can dry out. I have found that if you pour water over it, the water mostly runs off. One gets good water absorption with a spray bottle and no waste. If you have to carry that water for several hours on a hike and need it for drinking too, bring a spray bottle! In our case it was an outdoor canine agility match in sweltering heat, reaching 31 degrees Celsius in the afternoon. I had to supplement for my dog with a bandana rolled around ice cubes and held right over the his throat. Although the dog must run ***** (not even a colar), he kept his mental alertness with my neck chiller while the coat gave him the ability to last a course (and earn us a title as it happened). Well made and designed coat. It is also quick to remove which, in our case, is at the last minute before entering the ring.

Attractive, comfortable, functional

With her black coat and short tongue, my dog is extremely sensitive to heat. I bought a different cooling vest last year that basically consisted of straps that didn't keep the cooling inserts positioned against her body, and chafed her skin. We're so happy with the Swamp Cooler! It fits her well. I put my hand several times and verified that it doesn't insulate as human evap garments often do. It stays cool inside as it's supposed to. With this vest we've been able to walk and even run in temperatures 10°F warmer than what we could before. Well worth the price.
