I have a turquoise SMx air ride pad for sale. I've only been using it for a month, but my horse has a really short back and it nearly covers her entire back. No photos of it atm, but I can get some next weekend if you want. $100 cnd.
I also have a brown 36" pro choice cinch that I bought a month ago, but my horse lost a lot of weight and its too big for her now. $35 cnd.
Buyer pays shipping for both items.
