come to think of it, RRLs are not that expensive any longer as far as high quality denims,you might be able find on ebay for quite reasonable , besides you got a discount so , you are ok.
Yes you will find selvedge in your up and arriving denim. RRL uses japanese selvedge denims so there is a quality pair denim.
Slim fit is good, but not too slim and only difference is the leg opening less than 8 inches.
you are also buying the leather patch with RL on it and some back pocket designs. made in USA
they made alot of them.
overall you made a good choice.
the big difference between cheap denims and more expensive ones is good ones tend to stay in firm and taut with how ever you wear them, they will get soft and but there is still maintain good shape ..
