Don't buy the cair panels sysyem. I was talking to a saddle fitter yesterday and she was telling me that there is a fault in the design. There are two air 'pockets' (its not called that but anyway...), one at the front and one at the back. When you ride, the air all goes to the stitching the middle i.e. half way along underneath your saddle. It can create pressure points. I had a cair saddle that I was borrowing and she showed me how to feel for this. And I could feel it easily! my poor mare - I won't be using cair again untl they alter their design! I don't know how well know this is but everyone who was with me was surprised but they all agreed once they felt the saddle I'd been using. And this saddle isn't very old either!
When I bestride him, I soar, I am a hawk: he trots the air; the earth sings when he touches it; the basest horn of his hoof is more musical than the pipe of Hermes. ~William Shakespeare
