I have three sheepskin half pads pads (with the actual original skin attached), a mattes, a HORZE, and I think a Champion? I use the mattes and the champion under my jump saddle with no cloth pad, fleece right against the skin, because maresy has indicated that this is her preference :). I wash them quite often in MELP or Leather Therapy, hand wash cycle cold on the washing machine, dry flat, brush up a little, and they are holding up very nicely. No problem with the skin drying out.
BTW, I chose these pads because they had a āgulletā down the spine. I believe that the fleeceworks pads Iāve seen donāt have a gullet. It seems to me that a gullet in the pad pulls up a bit better into the gullet of the saddle.
So I donāt see any downside to using real sheepskin. I would worry that the āmanufacturedā pads might not be as sturdy. It seems to me they would be more expensive to manufacture, yet as they cost less, I canāt help thinking that some loss of quality or quantity has to happen along the way.
BTW, sheepskin is a renewable resource, in the sense that sheep (like trees) reproduce
plus I expect that the sheep are slaughtered for meat as well as their skins. Non-renewable resources are, technically, things like oil that are finite. But, yes, the sheepskin does represent a dead animal. I know my horse is always very interested in new sheepskins, they definitely signal something different than my other gear.
