Cool your horse without getting them soaking wet. Activate the cooling effect by submerging the rug into a bucket of water or sprinkling with a hose. Wring out to remove excess water and keep the horse dry; then simply put on the horse for an immediate cooling effect. Once the outside of the rug feels warm, reactivate the cooling by rewetting the rug. Ideal for cooling horses on the go, at shows and events, or when access to running water is limited.
