Jaipur Pro Polo Jeans
I just had to tell someone about these, These are the greatest pants ever made, 93% cotton, 7% spandex, basically a medium to heavier weight (compared to the womens riding tights I see) material. There were about $55 at horse lover. I have my suspicion "Tuff Rider" are the same thing.
I have black and will probably get a white or gray set for summer. But the black look really nice. They are cut like jeans, look like something a man would wear, the legs are wide enough and look good over conservative ropers, Theyd also be ok with lacers. Have the full seat, but it is invisible from the outside. Unless you feel them they really do look like a super dark flat black jean type pants, But they are soooooo comfortable in the saddle.
Only down side is the back pockets are kinda small and could either be deeper or have a button or piece of velcro on the top to hold wallet in.
