Do you feel the thicker ones have the same about of protection as the thin ones?
I love love love my Thinline pad. I have seen such a difference in my horse's comfort as well as mine. My horse has to see the chiropractor every few months and she has also noticed a difference in his back. I have the thicker black one for every day use and then the thinner white one for horse shows. I also trimmed it a tiny bit with scissors so you can't notice it with my hunter pad. I also like that they have many pad options. I think my next Thinline purchases will be the girth and some boots.
