A "built to last" graphic spans the back of the Carhartt Irvine Relaxed Camo Rivet T-Shirt, backing up Carhartt's own reputation for durable gear. Cotton-blend fabric keeps the shirt light and breathable, and a rib-knit collar and cuffs hold their shape through repeated wear. The relaxed fit sits close without restricting movement, and side-seam construction keeps the shirt from twisting during the day.
