The Ruffwear Swamp Cooler uses natural evaporative cooling to keep your dog cool. Soak it in cold water, wring it out, and fasten around your dog.
- Evaporative cooling exchanges the dog's heat as water evaporates from the coat's reservoir
- Temperatures drop through the phase transition of liquid water to water vapor, mimicking the cooling effect of humans' sweat
- Swamp Cooler's light color is designed to reflect heat from the sun
- Auto-lock buckles on each side of the jacket provide easy on/off
