After your ride is complete you may notice an unequal sweat pattern. Also, before girthing your horse, you may notice a void between the horses mid-back and the bottom of your saddle (if you place your hand under the mid-point of the saddle). These things could indicate that there is an area where the saddle is not equally distributing the weight of saddle and rider thus causing unequal pressure on the animal’s back. You can add or subtract felt shims to help alleviate the pressure, creating a more comfortable ride for your horse. The Pressure Relief Pad has a durable cotton duck top with a 1” Wool felt bottom. The pockets contain 1/2” Wool felt shims, which can be removed to better fit your saddle.
