  • The evaporative cooling process is what makes this vest work—simply soak the vest with water, wring it out, strap it on and heat is dissipated as the water evaporates
  • Wicking mesh layer on top facilitates evaporation and releases heat, middle layer absorbs and stores cooling water, and bottom layer transfers the cool to your dog
  • Light-colored fabric reflects sunlight and heat to increase cooling efficiency
  • Ergonomic cut wraps back and chest to offer a comfortable fit that stays in place; quick-release buckles allow an adjustable fit and easy on/off convenience
  • Attachment loop situated between dog's shoulder blades offers a clip point for a beacon light (light sold separately); reflective trim enhances visibility in low light


Sizing is based on girth. For girth, measure around the widest part of your dog's rib cage.
