To a great extent, the ultra heavy flannel (UHF) shirts define Iron Heart: heavy, rugged, but amazingly wearable. The 12oz fabric is woven with Aspero cotton from the foothills of the Andes mountains. They double brush it on the inside and single brush it on the outside, resulting in a very soft yet substantial, thick, warm and windproof flannel.
New for FW26, this overshirt represents a first for Iron Heart: an overdyed UHF in a solid colorway. To achieve this rich camel-brown shade, the shirt is first made using a regular yarn-dyed UHF fabric before being overdyed in the same color after construction. This process deepens and intensifies the hue, softening the fabric further while retaining the signature UHF heft.
Designed as an overshirt, this cut is an ideal winter layering piece, worn either as an outer or mid layer. Like their traditional work shirt, the cut includes classic patch chest pockets (complete with a pen holder) and button fastenings throughout. Where it differs is in its looser fit, straight hem, and split side-seam gussets, which are more characteristic of the mechanic shirt cut. Wear true to size for layering or a casual, relaxed fit, or size down for a more fitted silhouette.
