The Iron Heart IHT-1610L-WHT Longer Body Crew Neck T-Shirt in White is an old-school inspired classic produced in a heavyweight and once-washed 6.5 oz. Japanese Loopwheel Jersey that's appropriate for year-round use. This shirt is made with 100% cotton using specialized loopwheel circular knitting machines from the 1980's in Wakayama, Japan that operate at slow speed and leverage gravity to produce consistently tensioned and soft, breathable fabric that will remain durable for years. Using a classic fit, this loopwheel tee is produced without side seams for a knit feel on body that drapes, with a broad shoulder and an ideal length to be worn 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 a banded interior neckline, sleeves and hem to make a very special basic for the stylistically sound and self-reliant. The 1610L 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 1610L runs true to Iron Heart sizing and is made with a once washed, loopwheel fabric. With regular use, one can expect up to .5” of shrinkage in the chest and 1" of shrinkage in the 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.
