i find them true to size. a bit tight at first like any pants but after wearing them for a day i love them. be sure to order the correct inseam if you plan on using knee-pad inserts.
hope that helps
I think they are true to size! I'm a big guy and classically wear a 40/32 and I'm quite happy as they are comfortable and forgiving when I'm working in them
They seem to run true to size
