The Ruffwear Swamp Cooler™ Dog Harness combines effective evaporative cooling technology with the functionality of a lightweight everyday harness, helping dogs stay comfortable and active during warm-weather adventures. Designed for hiking, walking, running, camping, and travel, this innovative harness keeps dogs cool while providing a secure and comfortable fit.
Simply soak the harness in water, wring out excess moisture, and put it on your dog. The Swamp Cooler™ Harness uses evaporation to dissipate body heat, while the light-colored outer fabric reflects solar radiation and the mesh lining enhances airflow for improved cooling efficiency.
An anodized aluminum V-ring leash attachment point provides secure leash connection, while six adjustment points allow a customized fit for dogs of various shapes and sizes. Reflective trim improves visibility in low-light conditions, and an integrated light loop allows attachment of The Beacon™ Safety Light.
