Here's a picture of my new saddle pad:
I did also order a Thinline pad because I'm paranoid about protecting Mac's back as much as possible and I'm a sucker for a "therapeutic" saddle pad. Since the Saddleright didn't work out, I'll give the Thinline a shot. I use one with my dressage saddle and like it, but that one is too small to fit the new saddle.
Now I need to hit the trails - soon!
