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.

GREAT for Walking!

I bought this for use on vacation for our morning walks. I have a Rhodesian Ridgeback and if there is too much heat or humidity it saps her. this vest seemed to work really well! Thank you!! Divya thanks you too!

Not a great fit!

Not sure if it is the breed of my dog or what but it is not a great fit. Disappointed that it doesn't fit better and cover more of her sides. Had to return the first one because it was to small even though we measured and had two inches to spare it was way to small. Ordered the next size up and it fit but like I said not very good coverage on the sides by her front legs, she still gets sunburned.

Cooling vest

I’ve only had the opportunity to use it a few times but so far it seems to be helping my black coated poodle mix stay cooler. I’m hoping it gives me a chance to go out hiking and be back by 10 instead of 8. Also a few more sizes would be great. The Xs was to tight and the s is a bit baggy. Overall I think it might be the ticket to more pleasant hikes during warmer weather

I had to alter the item to make it fit him. The size around his chest was right but the garment extended below his waistline and pinched his *****. Its taking a while for him to get used to it.

Cooling vest

Sport loves his new vest and it helps him sleep though the night in bed, where he wants to stay.
