The CIRCLE Y Performance Wool Felt Saddle Pad is made with 100% pressed wool felt for superior quality – it's the best you can get. Loin relief design will not bind the horse's movement with cinch cut out. Wool will naturally wick away more moisture, release heat build up, breathe for a cooler ride, and is quick drying after use. The wool conforms to the horses back resulting in less slippage.
