Great on its own or as a base layer

For over a century, Carhartt has produced rugged workwear that stands up to the toughest jobs — this soft yet durable, heavyweight men's muscle shirt is a nod to that legacy. It offers side-seam construction to minimize twisting, a rib-knit crewneck that holds its shape throughout the day and a roomy fit that allows you to move freely as you tackle daily tasks.
