I disagree with anybody who says these shirts are a size larger than expected.  The sizing is exact in my opinion, if anything, slightly smaller than anticipated.  The shirts are great quality, heavy duty, attractive, single color shirts that have the tag printed onto the fabric instead of a separate piece sewn in (therefore nothing irritates or scratches your neck).  The pocket is sturdy and handy, and the button v-neck collar avoids the choking that typically is associated with T-shirts, and more stylish than just a v-neck that isn't button up enhanced.  If you order them in a taller size, you can run them through the washer and dryer and still tuck them in, looking sharp and well-groomed even after owning and wearing them several times through the laundry.  This is a great product, and deserves to wear the Carhartt brand - which is sewn onto the outside front of the pocket so that doesn't make you itch either.  Worth the money and I have ordered several because I like this shirt so well.  A casual shirt that is very comfortable, and yet doesn't completely compromise style - keeping a professional look.
