|Purchased new 3 years ago to perfect the ever-changing fit of my gelding as his work levels changed. This is the Skito "English Interpad" in black cotton quilt, seen here (website is painful, but products are fantastic) http://www.skito.net/products.htm. Includes entire set of fitting shims, wither/shoulder, bridging, and lift back. I chose Skito over Thinline/Mattes/SaddleFitter because this is not a slot type system and the shims have no hard edges. No ridges, pressure points, no predetermined slots, shims can be placed wherever it does the horse the most good. Bought new for $160, gently used, grab a bargain at $99 shipping included in lower 48.
