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.

Works like a wet swimsuit

I have a small dog and live in Florida. Our daily afternoon walk is at 4:00, some times the hottest time of day here. It's our schedule, so, he likes to keep it, regardless of temperature. We've already had some "feels like 100 degree" days. He went from walking and laying down every 5 feet, to completing almost the whole walk with just one lay down and very little panting. When he got home, his fur was actually cool under the vest. I would absolutely recommend this product. It worked for my best furry friend.

Nice concept but odd to put on

My dog is an 80lb pit/dane. Per the instructions to wet the vest first then put it on the dog is like putting a wet swimsuit on dry skin. He does not want me to put it on him considering he's completely dry yet the vest is cold and wet. After some patience and sweet coaxing, we get it on him and it seems to help but maybe a dog that likes water wouldn't mind this at all.

Jet stream cooling vest

Too small. Based size on other products. Not enough coverage to provide cooling. Too expensive.
