I don't know, but the girls who were riding them didn't seem to have a problem with them slipping when mounting up or anything. They may actually have some kind of fork in the front at the withers that keeps it from pulling over. I've got a bareback pad like that. The girth and stirrups attach to a hard plastic thing shaped like the pommel of a western saddle with no bars or cantle. The pad just sits underneath it. I don't use it much coz you get dirty, but it works better than just a standard bareback pad.

Well, if I had a horse that was any harder to fit than Bay, I'd surely consider it. We got ecurbh's to fit because it had so much rock in it, and still we had to make the custom pad to go under it to make sure it didn't bridge. Also might be good if you had to fit multiple horses with very different backs and only one saddle.

We chose ecurbh's for Bay, but it seems to fit Cyn as well. That was just lucky, with the cost of western saddles it'd be expensive to have to replace them whenever you change horses.

And of course, the cost of replacement was one of the reasons we chose the one we did... for less than $500, you can afford to replace it whenever you have a new horse with new needs.
