Details: Our pocket t-shirt debuted in 1992, and its rugged cotton design and clean looks made it a fast favorite among the hard-working folks who pulled it on. Though decades and trends have come and gone, there's a reason the K87 remains a classic. This men's t-shirt is made with heavyweight cotton built to handle tough days on the job. It has an original fit that gives you room to move and a soft feel that only gets better with time.
