Marine Layer took their bestselling selvage shirt (you know, the insanely comfortable one) and made it even more comfortable by adding stretch. It's lightweight, moves with you, and is long enough to tuck in (but you make the call).  They've updated this year's fit to be slightly trimmer than before, but the added stretch keeps it just as comfortable.
