I agree and disagree with it. Say, my saddle fits, however I still use Thinline pad. It's so thin that it doesn't interfere with the saddle fit, yet provides a good protection for the horse's back (I noticed the difference right away in their movements).
I'm not big fan of Trifecta though, because it has Thinline material only in certain spots, not all over. I'd much rather go with standard or ultra half-pad.
