When shade is low and the mercury is high, dogs can count on the Ruffwear Swamp Cooler Dog Vest to help get them outside. Strategic material choices and design offer solutions for the challenges that warm-weather exploring presents. The light-colored fabric reflects solar radiation and provides shading, while wetting the vest activates Ruffwear's evaporative cooling. This vest is designed for evaporative cooling in hot weather and is compatible with most harnesses. It achieves cooling through three layers: a wicking outer layer that facilitates evaporation, an absorbent middle layer that stores water for evaporation, and a comfortable inner layer that transfers the cooling effect to the dog. Key features of the Ruffwear Swamp Cooler Dog Vest include: * **Evaporative Cooling:** Keeps your dog cool and comfortable in hot weather. * **Lightweight Design:** Doesn't weigh your dog down during activities. * **Harness Compatibility:** Designed to be worn with most dog harnesses. * **Reflective Trim:** Enhances visibility in low-light conditions. * **Available in Multiple Sizes:** Ensures a proper fit for various dog breeds. * **Sage Green Color:** A stylish and practical color for outdoor use. The Ruffwear Swamp Cooler Dog Vest is a great choice for active dogs who enjoy spending time outdoors, even when it's hot. It has a customer rating of 4.4 out of 5 stars from 167 reviews.
