The Swamp Cooler Core™ is an add-on that provides cooling, extra lift-and-assist support, and additional stability for the Palisades™ Pack, Approach™ Pack, and Web Master™ Harness.
This three-layer chest panel features Ruffwear's Swamp Cooler™ Tech that uses evaporative cooling to efficiently disperse heat from the dog’s core when exploring in warm temperatures. To activate, wet the Swamp Cooler Core with water, use the hook-and-loop sleeves to attach it to the chest and belly straps of the pack or harness, then hit the trail!
