If you want a *real* durable shirt, get Carhartt. Period. They are more accurately described as average weight. But for the price, they're better than any other long sleeve shirt I've had in years. The neck is fitted and they are NOT tagged (although the tags didn't bother me) but overall they fit great; They are a good size and very comfortable. If weight is your main concern, pay for Carhartt again, but for a fraction of that price, they're MUCH better than comparable but paper-thin Revain shirts labeled 'heavyweight'.
