Keep your pup comfortable during hot weather with the Core Cooling Vest. This innovative vest uses water evaporation to regulate your dog's body temperature, so they can enjoy outdoor adventures without overheating. Simply wet the vest, wring it out, and secure it with quick-release buckles—re-wet as needed throughout the day. Features a two-way zipper for easy harness or collar access, lightweight polyester and air mesh construction, reflective accents for visibility, and a light color that reflects the sun's heat. The athletic cut provides a comfortable fit while side adjustment points ensure a secure, customized fit. Machine wash gentle or hand wash, then air dry.
