Tailord sportsmans and RJ classics are awesome they are annoying at first but after 2-3 times wearing them they feel
If you want a cheaper brand I would look at Horze Loverz (I think that's what it's called). It's a website and a lot of their products are cheaper than other places.
Tailored sportsman are really nice, make sure you go to the the store to try them on, I ordered mine online and they kind of fit me wierd. They are a little loose on my legs but fit my waist good :) the next size down fit my legs but was too tight around my waist XD
RJ classic and tailord sportsmans are probably the most popular you could try Rophmers but my barn isn't a big fan of then and we are a big show barn
