Turn summer's heat from grueling into cooling with the Chill Seeker Cooling Vest. To activate its evaporative cooling technology, just soak the vest in water and wring it out. As the water evaporates it absorbs heat and cools your pooch for ultimate summer comfort. No chemical coolants, mesh layers allow for air circulation, reflective panels, size adjustable, easy to put on and take off and a slit of leash or harness connection!
