They make motorcycle chaps that are 100% USA made(leather, zipper, snaps). They are more enclosed, than standard chaps. The legs have ZERO seams(except at zipper) and are 5-5.5 oz leather!
Very happy with them, give them a look for chaps/Gloves.
Have you checked out the Chaps sold by Pennleather.com? Small little shop in Palmyra, PA. He hand makes his chaps and has a super design so you don't have to fight with getting the zippers zipped. Affordable. Really happy with mine.
I just got a pair of 2nds from B bar B yesterday. They are great. They said the 2nds would have obvious cosmetic defects but a thorough inspection only revealed a couple of inconsistencies in the grain of the leather. Definitely a high quality product.
