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.

Helpful but not perfect

This vest is made well. I bought it to use on my Rhodesian Ridgeback during summer runs. We have the Swamp Cooler vest for my vizsla and that chafes her armpits while running. This doesn't look like it will chafe as much since the armpits are cut higher. I do wish that it covered more of his body even though the Ruffwear team told me this is a proper fit. It's also not the easiest thing to put on, but once it's on it fits snugly.

Great cooling gear—could use one tweak

This is a great piece of cooling gear! I suggest ordering it as small as possible for your dog, ie, if your dog is in between sizes like mine, who measures 27”at the girth, go with the small instead of the medium. This keeps the cooling panel tight against the dog’s body and provides more efficient cooling. However, the one tweak I would recommend is adding the snap closure of the end of the zipper as featured on the Cloud Chaser jacket, as when the Jet Stream is fitted tightly, it can tend to unzip partially. A tight fit is preferred, and a snap at the end of the zipper should keep it from wanting to open up. Just my two cents! Happy trails!

It's alright

I live in Hawaii and take my pitbull on many hikes. He doesn't have a lot of stamina and the heat wears him out, but he LOVES to go hiking!! So I thought I would give this vest a try. I used the dog's water bowl and dunked the vest in to get it wet once we were out on the trail. He has no issues standing and waiting for me to get it on him correctly. I think it helped keep him cool a little better than normal.... Hard to tell. But it did rub his skin raw under his armpits, and it dried out rather quickly (~1hrish). We typically do about 5 miles with him and are out for 3-4 hours. I don't know that I will use this again on him. For the little bit that it did cool him, it's not worth the raw skin.

Jet Stream Cooling Vest

Hasn’t been used yet, it’s too cold here in Oklahoma. Plan to use it this summer, then I’ll know more. A friend who has used them recommended it. We shall see.
