This is very uncommon to me. I typically ride with a very loose
cinch on the one mare-you can see air at the bottom.
I am not fond of the cinch the saddle comes with-replaced both mine
with a neoprene, and don't have any slipping.
A good example-this weekend on a ride I dropped my sweatshirt.
Not being fond of dismounting, I grabbed mane and hung off the
side of the horse to pick it up. The saddle did not slip at all.
I also use the skito equalizer pad, perhaps the pad has someting
to do with the slipping. The skito pad is shaped to the back.
