Substantial, warm, and windproof, Iron Heart's 12oz slubby heavy flannel (SHF) shirts carry all the durability and comfort their ultra-heavy flannels are known for. Crafted with slub yarn cotton, these shirts showcase a more pronounced texture and rugged feel compared to traditional flannels. While the fabric’s outer face exudes character, the reverse side is double-brushed for a soft, cozy feel. Available in a black/navy herringbone check and cut in Iron Heart’s signature work style, these shirts have been updated for FW24 with sturdy four-hole buttons, offering a secure fastening upgrade over previous models' cat's eye buttons.
