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.

Hot dog in the city

We bought this for our Akita/St. Bernard mix who lives in Florida. He hovers around 90-95 pounds, so right on the line between a medium and a large. We originally got the medium and exchanged it for the bigger size. Even though the sides and top of the vest are a stretchy material and we were able to close it, our dog was very unhappy with the smaller size. We were able to keep the vest moist by pouring water down his chest and onto the gray mesh. He was noticeably more comfortable (he gets visibly cranky when he's too hot) and was game for going the full 4 miles of our hike when he normally wants to stop after 1. The vest itself is very easy to clean - we washed it in cool water with the rest of our hang dry stuff - and folds up nicely to be stored away. Would definitely recommend for dogs who get overheated easily.

Best Ruffwear product!

At this point, I think I own nearly half the Ruffwear product line, but this is the most useful and necessary product I own. I live in SoCal, and my vizsla and I run daily. This vest allows me to take her in temps that I otherwise wouldn’t. I just soak it briefly (my daughter’s plastic kiddie pool works well for this), put it on her, and go. It stays moist for at least an hour and we can re-wet it at stream crossings or even water fountains. As others have said, the zipper could be a bit more robust, but otherwise, it’s a great product.
