Keep your dog cool on warm days with this vest that’s designed to be soaked and worn. The moisture from the vest combines with heat from your dog and cools via evaporation, just like a quick dip in the lake. Reflective details help in low light while the zipped closure ensures it’s easy to get on and take off while remaining comfortable due to the formfit construction.
