Aha! You got the 29 Japanese Khakis? I was eyeballing them for a couple of days and then poof, gone. I've got a handful of rivets and have noted minimal, if any, stretching in the waist, but then again 29 is a spot on fit for me (no tension=no stretching). YMMV, however. Others may have different experience (NYR and others have a slew of rivets and have been wearing them for longer). PS. if you decide to part with them, please pm me.
