Liner adapted to the Reinvent rugs. Outside in soft, smooth polyester with breathability, inside in polyester mesh that transports and absorbs moisture and thus helps to maintain a comfortable and dry temperature close to the horse. Attaches to the Reinvent rug with Velcro and snap hooks at back. Easy Velcro fastener on shoulder. With removable elastic girths so that the rug can be used separately if necessary. NOTE: this is a liner rug adapted in size to fit under an outdoor rug; it is therefore slightly shorter in back length and in depth to prevent moisture from outside being drawn under the rug.
