The Ruffwear Swamp Cooler Zip Dog Vest is designed to efficiently cool dogs during light and fast, high-intensity adventures in warm weather. It utilizes evaporative cooling to keep your dog comfortable on sunny hikes and fast-paced explorations. The vest features a three-layer construction designed to cool your dog's core. The outer wicking layer reflects heat and facilitates evaporation, while the absorbent middle layer stores water for cooling. This updated Swamp Cooler Zip is made with durable polyester stretch fabric, ensuring an improved fit and color retention, ready for any adventure. It is easy to use: simply soak the vest in cool water, wring out the excess, and zip it onto your dog. As the water evaporates, it draws heat away from your dog's body, providing a refreshing and long-lasting cooling effect. Key features include: * **Evaporative Cooling:** Keeps dogs cool through evaporation. * **Three-Layer Construction:** Wicking outer layer, absorbent middle layer. * **Zippered Closure:** Easy to put on and take off. * **Durable Fabric:** Polyester stretch fabric for improved fit and color. * **Reflective Trim:** Enhances visibility in low-light conditions. * **Light Loop:** For attaching a Beacon light for added safety.
