The Ruffwear Core Cooler is an add on attachment that attaches onto any of Ruffwear's backpacks and harness to offer support and protection during backpacking, hiking, or any other outdoor activities in the hot summer heat. This chest guard uses a three-layer design made with air mesh and 420D nylon ripstop. Once the Core Cooler has been dunked in water, wrung out and attached, the inner core will absorb the water and the inner layer will draw the heat from your dog's chest and transfer the cooling effect while the outer layer will assist in evaporation. This guard also helps prevent abrasion to the chest and belly area while also distributing weight and tension when wearing a backpack or if you ever need to lift or assist your adventure buddy through tough terrain. 

Easy to attach and remove, the Core Cooler uses a velcro hook and loop system to secure itself onto harnesses or backpacks. Available in a variety of sizes; Please see the specifications tab for more information.
