The Matrix Traditional Schooling Liner complements the technical features of the Matrix Traditional Half Pads while acting as a dirt barrier to keep the half pad clean. Under the saddle is a single layer of ET, a non-sli, anti-friction fabric that will keep the saddle and liner securely in place without interfering with the horse's range of motion or muscle development.... (read more) The thin membrane of fabric will flex with the half pa, rather than wrinkling like a baby cotton pad. Highly breathabl, ETC wicks moisture rapidly away from the horse. Under the leg is a thin layer of 1" square quilted ETC for a traditional pad appearance. The billet straps of the Matrix Half Pad pass through buttonhole slots in the liner to keep pad and liner together for added security. Machine washabl, dryer saf, the liner can also be bleached (use color safe bleach for colors). For Traditional Matrix Half Pads (see Item #27-62 , 27-72 , or 27-82 ).
