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 vest!!

I have a chocolate labradoodle who does not tolerate the Utah heat very well. The cooling vest has been amazing! The only thing I regret is not buying the vest with the cooling mesh all around. The spandex orange on top dries out pretty fast. Overall great investment!

Great for active aussie mix in SoCal!

It works like a charm! (It doesn’t hurt that I live in the exact climate these vests work best in— sunny, hot and dry) I have a young active pup who is obviously more active with it on than off— which is perfect for summer time! She was right on the edge for sizing so I assumed up and got a small, it fits great. Easy to put on too and took very little adjustment for her to get used to it. So far its taking a good beating of dirt, sand, water, grass and more, I would definitely recommend this product to other dog owners!

Good in hot weather

Easy to use; ran tap water over the vest to completely soak. Wrung out the excess water & put it on my Boston terrier (13lbs, XXS vest). She stayed relatively cool while walking downtown in the southern heat and humidity for over an hour. Would likely last longer if colder water was used.

Summer Essential

This vest is great for cooling down my service dog. Its easy to put on and fits under her harness. I love that she can enjoy sumer walks without being uncomfortable. I am especially pleased that she is not left wet or smelly after using the vest. A great buy for sure.

Cooling Off

I am very happy overall with the Jet Stream cooling vest. My dog’s core temperature is noticeably lower when he wears the vest in the dry heat. The spandex on his back also keeps his back noticeably cooler. The only thing that is not perfect is the fit. He is an 80lbs American Bulldog who has a broad chest/ribs but narrow waist. The size large is slightly loose at the waist but I think if I buy the size medium that it will be too snug on his chest. Overall I am very happy though and would purchase it again.
