On the Cavallo All-Purpose English Saddle Pad, memory foam sits on either side of the spine to enhance the function of the saddle gullet, allowing your horse a place to put his backbone and use his stricture properly. Shock absorbing memory foam provides a gentle massaging action as it bounds back in anticipation of the next impact. Seat bone cues are easily transmitted for disciplines from Dressage to Jumping. Firm poly fiber sheets have been inserted alongside the protective memory foam inserts“ these poly fiber sheets create internal stability, which serves to further equalize the load in high-performance sports. These panels produce an inner equilibrium that, even in very active rider movement or saddle stress situations, will allow for more complete utilization of the horse's scapula. This saddle pad offers a great fit between horse and rider. When using this pad, take care not to tilt the saddle too far back on the loins.
