I was looking at a treeless trail saddle...the kind that look like the Western saddles (w/ pommel and cantle). I would be using it also for mounted patrol, and so that's why it has to look like a western saddle (requirement of our uniform). I saw one that I thought I might like, but when I read the measurements it talked about measuring the circumference of the thigh. Then I Googled it and found that this is how they're measured. But then I also saw that when it says 16", it's not really a 16", but more like a 14".
So how are you supposed to measure these things to make sure you're butt fits in them and compare them to other saddles' measurements? Is there a conversion chart they go by or something? Is there a reason you can't measure the seat the old fashioned way? It sounds like an attempt to be "hip" if you ask me...but what I would really like to know if what's under my "hip" is going to fit in the darned thing.
