The Ruffwear Jet Stream efficiently cools dogs during light and fast, high-intensity adventures through shading and evaporative cooling. In warm climates, dogs typically stay cool by seeking shade in the heat of the day. The light and sleek Jet Stream uses shade-providing spandex over the back, while Ruffwear’s three-layer evaporative cooling chest panel disperses heat from the dog’s core. To activate the Jet Stream, soak in water, wring out, zip on your dog, and go.

Perfect !

Just what I was after-the Jet Stream Cooling vest is thin but very effective ! My little Frenchie just thinks she has a shirt on. Great for car travel and warm walks in the Southern California desert. Thanks so much ! Susan and Della

Fabulous weather protection

I’ve only used this jacket on my service dog once. Because she goes everywhere with me I wanted a product that was easy to get on and off while at the same time staying in place. This product is wonderful quality, kept her dry in the rain and did not slide around. I love it!

Works great for my. Low Rider

I bought this for my Dachshund because she's so low to the ground and gets hot very quickly from the heat reflecting back at her under carriage. It worked great. We did a lot of walking this summer in 90+ degree heat and it kept her a lot more comfortable.

Really Keeps My Service Dog COOL!!

Many of the clients from our service dog organization use this vest and the Swamp Cooler vest. I love how my Golden Retriever was kept comfortable during our summer hikes and outings. The fit was perfect too! Troy and I are happy campers! : )

Very nice fit, works on short hair dogs

I really like the fit and material of this. It works very well for my single coated, short haired dog. It would not work well for a long haired or double coated dog. It provides high visibility, and I love the colors. One thing I added was a snap at the bottom of the zipper to make it easier to zip up.
