The Swamp Cooler™ Harness is a trail-ready, all-in-one cooling solution for dogs exploring in hot conditions, now with a third leash attachment point on the chest. Integrated directly into our three-strap harness platform, it leverages our Swamp Cooler™ technology to pull body surface heat away through evaporative cooling. Dial in a secure and comfortable fit with six adjustment points, lift and assist with the quick-grab handle, and stay connected with three leash connection points as you head out together on your next summer endeavor.  

How does Swamp Cooler™ Tech work? Learn more here about how that refreshing, just-stepped-out-of-a-lake feeling known as evaporative cooling helps keep your dog cool. Check out the Swamp Cooler™ Collection.

Reviews Summary
Customers say this cooling harness helps their dogs stay comfortable during hot weather activities. Many note their pets can walk and hike longer without overheating, especially those with thick or dark coats. The harness fits well on most dogs, though some mention sizing runs large. Users appreciate the sturdy construction and convenient handle. While most find it effectively retains moisture for cooling, a few note it can collect sand and may require occasional rewetting during longer outings. The harness generally receives praise for its comfort and functionality, though some wish for additional color options beyond the light-colored design.

    New swamp Cooler Harness

    We just bought this harness for our Aussie who gets extremely hot in the summer months and this both fits great and appears to be extremely comfortable for her! I would recommend anyone who has a dog who does better in the winter months to grab one of these for the dog days of summer!

    Great harness. Dog likes it.

    Really nice harness. Lots of features. Excited to try out the cooling feature when the weather warms up. Customer service was quite helpful with size recommendation. It was a little tricky to adjust the fit on my dog, but once I got it, it worked well.

    Woof! Woof! 2 Paws Up!

    My hooman loves this harness and I don’t mind it at all! It’s light weight and breathable, easy to wear with buckles to adjust size, I am an old man (I turn -7 this year and I am ALWAYS hot) so my hooman got this for me to relax in and now Im cool all the time! Hoping the team will design one olin navy blue woth waves all over it!

    10/10 I recommend for all the other Senior out there, we might be young at heart but we are also hot as the sun!

    Much Ruffwear, many harnesses. This one’s my favorite.

    The fit and comfort of these harnesses are significantly better than the than the old Webmaster, which I used for over 15 years. I’ve never known an RW harnesse to wear out, and this is not exception. Also makes picking up the little ones so much easier. Handles are important! I’ll never be without an RW harnesses.
