Ingenious design features three shim pockets on each side of saddle pad, giving you the flexibility to customize the shim configuration to relieve pressure points, correct saddle fit or fill muscle deficit areas. The 3/8" shock-absorbing EVA sport foam inserts allow you to easily convert from a built-up pad to a bridge pad for use on multiple horses to address saddle fit and conformation issues. Easy-to-clean canvas top pairs with a high performing wool blend felt liner that wicks away sweat to evenly cool your horse. Extras like a butterfly cutaway design for increased leg contact, a leather contoured spine that keeps center of pad locked into place and lifted into saddle gullet for increased airflow, and premium genuine leather wear leathers take this pad to the next level. Measures 30" x 30".
