What brand name of riding breeches should I buy for schooling?

I am petite and like both full seat and knee patches. I want breeches that are all cotton with a bit of stretch and are cool. I just about sweltered in my Kerrits. I just want something simple and cool for schooling

I love Dublin. Get them on Dover closeout for around $20-40. They last forever, are thick enough to be warmish in the winter, but really cool in the summer. They come in both knee patch and full seat. Devon-aire won’t last long though.
