The Ruffwear Swamp Cooler Zip Dog Vest is designed to efficiently cool dogs during light and fast, high-intensity adventures in hot weather. This vest utilizes shading and evaporative cooling to keep your dog comfortable. Its three-layer construction actively cools your dog's core. The outer wicking layer reflects heat and encourages evaporation, while the absorbent middle layer stores water for cooling. A mesh lining ensures your dog stays dry and comfortable.
