Made with lightweight material, this vest is the perfect way to keep your dog cool on hot days or extra long hikes. Uses evaporation to create cooling so you can simply wet it with cool water, wring it out and put it on. As the water evaporates, your dog's temperature lowers. The light colour and reflective material help by deflecting the sun's heat. Easy on/off design is adjustable with quick release belly straps. Two-way zipper to access harness/collar attachments. Constructed with lightweight polyester and air mesh inner. Two side adjustment points with Nifco quick release buckles. Uses evaporation to create cooling. Centres the cooling action on the dog's core. Reflective accents, athletic cut and styling.
