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.

Cooling wear

Got this for a pup who does not do well in our summer heat on the Treasure Coast of Florida. The jet stream seems to help her walk a lot longer than before wearing it. Cannot wait until summertime to try it with her. If it works well, I will get another one for my other dog. Thanks!!

Really fabulous product that works and isn’t toxic

My Golden retriever overheats easily but he’s a chewer so I worry about cooking pads with gels etc. you just soak this vest in cool water, put it on and it keeps him comfortable and happy for hours without me worrying (especially in car) that he’s getting into toxic mischief. Thank you roughwear for being #1 to our babies as always!

Ok but!

I have a lanky Boxer with a very deep chest, I had to return the size recommended and get next one up, it worked well but found the “arm holes” too baggy and the material across the chest is a bit too narrow considering that’s where it’s needed most, if that’s sorted it’ll get 5 stars because it’s and excellent idea.


Thank you- I will pass your comments onto the design team

We used the vest on a truck trip from Las Vegas to San Antonio. We wanted our husky puppy to be comfortable in the back seat of our truck (air-conditioning in 100 degree temps can be a challenge). The vest stayed cool & we rewet it every 3 hours. Dog was very comfortable & slept most of the trip. Vest was very useful on walks in the humidity of San Antonio too!

Perfect fit

I bought this for my Service Dog as I wanted something that would go under his vest or under his everyday harness while we did our Dog Parkour. This fit perfectly, was easy to put on, was easy to be rewet and seem to do the job.
