This special edition Wet Reveal Bandana starts as a solid color when dry and reveals fun smiley faces when wet. The Canada Pooch Chill Seeker Cooling Bandana keeps your pet cool and in style. No chemical coolants - just add water to initiate the evaporation cooling effect. The water-retaining fabric keeps your pets cool on hot, dry days. The mesh layers allow for air circulation and the bandana snaps in place for a secure fit.
