That looks like very poor quality leather to me. Leather like that is most often seen on saddles that are made in India or some Asian country on a cardboard tree. Unfortunately, I don't know anything about the brand itself, but I
wouldn't buy that saddle.
Just looking at the ad for it, it says it has an 8 inch gullet. Do you really need one that wide? Most FQHB saddles have a 7 or 7 1/2 inch gullet and that fits most standard sized stock horses.
