I find they rip at the crotch when I'm working. Terrible seam work. Wranglers are better cause they don't rip (Bless the fucker who designed the diamond seam for us lads who lift things properly), but all my jeans are stained to shit if I work in them at all, and they all stretch out more than a yoga instructor. I suspect there is less denim and more elastic in them these days, because I didn't use to have this problem.
