The Cavallo Western Barrel/Endurance/Stock Saddle Pad is already shaped to your horse's top line, allowing ample wither space. Memory foam ensures that pressure and weight are not continual, but yielding. Excellent for all sports requiring lateral flexion. The maximum defense against back pain, yet still thin to maintain feel. Fits like a glove. Firm poly fiber sheets are inserted alongside protective memory foam, creating internal stability which further equalizes the load in high-performance sports. By creating an inner equilibrium, these panels allow for more complete utilization of the horse's scapula, and an unparalleled fit between horse and rider.
