Carhartt's pocket t-shirt, which first debuted in 1992, quickly became a favorite among hard-working folks for its rugged cotton design and clean look. Decades and trends have come and gone, but the K87 remains a classic for a reason. This men's t-shirt is made from heavyweight cotton, built to withstand tough days on the job. With a loose fit that offers freedom of movement and a soft feel that improves with time, Carhartt continues to be a staple in workwear. After all, appearance matters.
