Wedged shim inserted between base and closed panels. Perfect for those who want the classy look of the closed panels (especially with a matching color/material) but need a little lift in front to balance the rider for horses who might be downhill where the saddle wants to side or who have less curvature than the Ghost base. These work just fine with velcro opening panels too, and sometimes are a bigger solution than the felt shims that can go inside the panel.
