This product is the trim-to-fit shim only, saddle pad not included.

What is ThinLine?

ThinLine is a thin, shock-absorbing nonslip breathable foam. It is endorsed by surgeons, master saddlers, riders, and veterinarians.

Where is the ThinLine?

It is sewn onto the panel of our Western saddle pads which have an open pocket, allowing you to place saddle fitting shims exactly where you need them.

ThinLine material not only improves saddle fit, but also provides comfort and protection.

When you see ThinLine sewn onto any Western saddle pad, there is a pocket for you to add inserts, also called shims.

Our exclusive foam makes saddles fit better, and horses more comfortable.

Inserts stay put without shifting and you may stack up to three sets. We do not divide the pocket, allowing you or your saddle fitter to place the inserts precisely where your horse needs them.

If you find you no longer need inserts, just remove them and keep all the great benefits of your ThinLine Pad!

Western Saddle Pad Shim Colors

ThinLine+ saddle shims are available in black only. ThinLine shims may arrive in black, brown or white. Since Western saddle shims for horses cannot be seen inside your pad, color is not an issue.

Please note: Bridging Saddle Shims for Swayback – If your saddle is bridging, you are missing contact in the middle of the horse’s back and there is too much contact at both the wither and the cantle. When using bridging shims, we recommend you start slowly. Use only one or two at a time. You will discover your horse will begin to lift their top line and develop more muscle with ThinLine. Once the muscle is developed it is often possible to remove one or all of the shims. Good news: you keep your ThinLine pad and horses continue to use their backs correctly.

How your horse should look – no dry spots in the sweat patterns
