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.

The vest is the BEST!

The vest works just like you said. It keeps my dog cool even if he’s in the sun. Thank you!!!

Keeps the furball cool on runs and hikes

This is probably one of the best purchases we've made for our husky x malamute it really does help her stay cool when it would be too hot for her otherwise. It is a bit loose in the chest, but it still works as intended.

Pretty good

I works really well. My dog stayed nice and cool all day. The only thing I didn’t love was that first day out it was stained. Washed it multiple times and the grass stains wouldn’t come out. I still really like the product though. It does the job it was intended for and I’ll be ordering more.

Comfortable and lightweight

I have only had the chance to use it once so I cant truly give an in-depth was great and it did not seem to effect our 60 lb Alapaha Blue-blood Bulldog puppy ...he seemed quite comfortable and not bothered while he wore it...hoping to use it more often... soon we plan for a trip...we live in Savannah Georgia and its ALWAYS hot here...he is not a great fan of the outdoors and we hope this will change that...Love your products and his harness as well.

Cooling vest works

My dog really likes the cooling vest, the top is prone to prickle and thread pulls and for our use we could have uses a sturdier material. My dog is running through the wood, briar patches and all. But we both love it's cooling ability
