Cooler rugs are breathable rugs that are used to prevent chills on sweating horses as they cool down after exercise. They are designed to wick moisture away from the horse's coat to the rug where it evaporates so that the horse cools down gradually. Cooler rugs can be placed under a turnout rug or stable rug to help a horse dry off after exercise on cold days and can also be used as an under blanket or rug for extra warmth in the winter.
A fleece rug can also be used as a substitute for a cooler rug.
