ThinLine pads have an open pocket and as a result, you can place shims exactly where you need them. The pocket has room for up to three 1/4 inch shims in the same location. When stacking multiple shims, place one just behind the other to create a seamless transition.

Bridging Shims are used to support hollow or sway backs. ThinLine foam encourages horses to lift their back thus developing better muscle tone over their toplines.

Bridging shims are a simple way to create the missing contact. Swayback or not, you may find bridging shims to be the easy solution.Horses will often develop better topline in ThinLine.
