The Iron Heart IHT-UTIL-BLK UTILITEES Crew Neck T-Shirt in Black is an old-school inspired classic produced in a medium weight and once washed 5.5 oz. Japanese Loopwheel Jersey that's appropriate for year-round use. This shirt is made in Wakayama, Japan with 100% cotton using combed yarns on specialized loopwheel circular knitting machines from the 1980's, which operate at an extremely slow speed and leverage gravity to produce consistently tensioned, soft, breathable fabric and will remain durable for years. Using an original tube-tee fit, this basic is fitted and drapes closer to the body with a natural elasticity and an ideal length to wear tucked or untucked for modern, vintage-styled grit. This Crew Neck is simple with carefully considered construction details like a rib bound crewneck and flat-locked seams for the sleeves and hem to make a tee for the stylistically sound and self-reliant. The UTILITEES Loopwheel Crew Neck T-Shirt strikes the balance between classic and modern applications, making it a future heirloom, a year-round go-to, and a basic that will perform over years of wear.

Iron Heart sizing is graded in small increments. The UTILITEES runs on the small side of Iron Heart sizing, and is made with a once washed, loopwheel fabric with most shrinkage removed. With regular use, one can expect minimal shrinkage in the chest and length over the long term. Consider going with the larger of your size range in Iron Heart or the next size up. 


Our Method of measuring is different than Iron Heart. We recommend consulting our Sizing Guide and using our Virtual Size Chart to reference our Method when purchasing.
