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.

Jet Stream Cooling Vest

This has been a great addition to our dog Ajei's Ruffwear wardrobe. We do a lot of mountain biking with her and she now finishes her rides with much more energy with the vest on than without.

Great product, overall quality could be better

This vest DEFINITELY works. However, after only 2 light uses there is a hole in the vest. That's my only complaint to be honest. Otherwise, it's great.

Give your deg some relief!

Wally wasn't a huge fan of getting this on, but he endured, and it enabled him to run full speed again. This summer, his endurance went from far beyond mine, to walking after a mile and a half. After a couple weeks training, I figured it was heat related, and this vest proved that correct. Even in 95°F heat and high humidity, Wally was able to actually run for 2 miles in this vest.

Cooling vest

I have a working bloodhound who overheats quickly while trailing in the heat. This was the perfect item to remedy this. Quick shipping too
