Limited Edition by Reinsman! This APEX wool pad is 100% pressed wool felt for superior quality -- it's the best you can get! It is naturally shock absorbing and moisture wicking. Loin relief design will not bind the horse's movement with a cinch cut out. Contoured spine for a great fit against the horse. Size is 30 x 30 and 3/4" thick. It is over-engineered for maximum performance!
