When there's little shade and lots of heat, let the Ruffwear Swamp Cooler vest help your dog enjoy the outside. Strategic materials and design help solve the challenges of warm-weather walking.


  • This vest is the highest-coverage cooling option in the Ruffwear Swamp Cooler™ collection
  • Wetting the vest activates the Swamp Cooler tech for evaporative cooling—like they just stepped out of a lake
  • Just give it a soak, put it on your dog and go; when it dries, resoak it to recharge it
  • Light-colored fabric reflects solar radiation and provides shading
  • Relaxed fit for maximum shade with UPF 50+ coverage
  • 3-layer construction cools the core
  • Wicking outer layer reflects heat and facilitates evaporation
  • Absorbent middle layer stores water for evaporation
  • Mesh lining keeps dog dry and comfortable
  • Side-release buckles for easy on/off
  • Leash portal on back is compatible with most harnesses
  • Reflective trim for visibility in low-light conditions; light loop for attaching The Beacon™ (not included)
  • Solid-color mesh and ripstop shell fabric are bluesign® approved
