The Ruffwear Core Cooler™ is an add-on that cools dogs, adds additional support when lifting and assisting, and further stabilizes packs and harnesses. This three-layer chest panel uses evaporative cooling to efficiently pull heat from the dog’s core during warm temperatures and high intensity activities. To activate, wet the Core Cooler with water and wring out. The Core Cooler easily attaches to Ruffwear harnesses and packs using hook-and-loop sleeves:

Core cooler

I bought this for my sons dog. He said there was some chafing but he thought he just needed to do some adjusting He said that this product does work and does a good job. He is very pleased with the core cooler and web master harness

Beat the social heat!

This really helped we attached it to the webmaster harness and he wasn't complaining about the heat at a few min. I only wish they made one for humans.

Keeping cool in Florida

I live in Florida and hike often with my Catahoula. We try to stay near water but even then it can get hot, really hot. This Core cooler by Ruffwear is used with the singletrak pack. It is perfect for keeping my big boy cool. I highly recommend Ruffwear! I also have an older version of the swamp cooler that I use on my Pitbull rescue. It has held up wonderfully and keeps him cool as well.
