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™ or Web Master™ Harnesses.

Unbelievably Awesome

I've been a Ruffwear Fan or years now and never question the quality of their products or ability to preform as stated! The the swamp cooler is a life and game changer for my 22 lb kid who loves being in all the action. But will start to over heat when it's over 73 degrees out. Last week we put the vest on and never needed to step back inside_ to seek an air conditioning room for him. With the vest on he was completely comfortable and enjoying the 90-100 degree heat we had. There was nothing slowing him down or holding him back from being out doors with me when it was on. The product is unbelievable awesome and a must have item if your a dog owner!!! I worry much when it comes to a warm day and him being outdoors. There are no more worries or concern to have when the vest is on. Yes, you just wet, ring it and put it on. Raider has a complete Ruffwear wardrobe and the size is the same for all of his Ruffwear Gear. I can walk into his favorite pet store and just grab an item and know it will fit. From jackets_ to harnesses it's_ all the same size! I've invested well over $500 in his Ruffwear Gear and not once questioned_ the price. You get what you pay for! I just don't recommend the brand I also have purchased items for friends who question the price. Just to prove the point you get what you pay for and made them Ruffwear Believers too.

Tilly Jane


Tilly is a black labradoodle and very sensitive to heat. We purchased the swamp cooler and had our first opportunity to try it out in nearly 100 degree weather. WOW!!! It really works.


Love it!

Grateful for the recommendation on the fit! if your dog is at an in between size do not hesitate to size down! We are getting ready for some hiking and we're super excited to use it!


Great well made

On these hot 100 degree plus day it allow us to go on our 6 mile walk without Larry getting overheated. I have used as a cooling method when returning from our walks !


Very Nice but til Big for the size.

Unfortunately the vest is to big, too big for. My dog measures 43 cm around the thorax, so I bought the xs size. But it is too big.
