Ultra Heavy Flannel Herringbone Work Shirt - Black

To a great extent, our ultra heavy flannel (UHF) shirts define Iron Heart: heavy, rugged, but amazingly wearable. This work shirt is in an exclusive Iron Heart designed black 12oz fabric, woven in a subtle herringbone pattern with aspero cotton from the foothills of the Andes mountains, double brushed on the inside and single brushed on the outside, resulting in a very soft yet heavy, thick, warm and windproof flannel.
