Horse rugs (blankets) serve far more purposes than simple warmth. Usage scenarios include stable blankets for warmth, turnout rugs that are waterproof and durable, and cooler wicks that dry a sweaty horse after exercise.
Materials range from breathable cotton and polar fleece to waterproof yet breathable laminates like Gore-Tex. Their efficacy includes regulating body temperature, keeping the horse clean and dry, protecting from insects, and even preventing a winter coat from growing too thick for horses in consistent work.
Choosing a rug requires understanding "denier" (fabric strength) and "fill" (insulation weight). A rug must fit well-too loose can cause rubs and tangling, too tight restricts movement. The right rug manages the horse's environment, reducing stress on its system and conserving energy it would use to stay warm, thus supporting overall health and condition.
