Thinline pads - opinions?

Please, share! :)

I have a couple of the regular ThinLine pads (contour and western round skirt). They work well for keeping the horses comfortable and moving freely, and they're definitely non-slip. I use mine over thin pads or blankets.

I have the ultra thinline, I LOVE it! I am able to do sitting trot better with the ultra thinline & its comfortable for my horse

Thanks, folks! I got Ultra myself, but... Isn't it TOO thin? (I use it over the square pad)
