I can't honestly answer about the fit/size but I was forced to for the review. I bought the pants for my 13-year old son who is growing like a weed (5'11" already!) so I didn't know what size he needed.  The only thing I can say about the fit is the legs seem to be a bit on the narrow side.  These are really nice, really well-made pants. He was very comfortable in them and he absolutely hates pants.
