Iron Heart’s Slubby Heavy Flannels turn up the texture on their signature winter shirts.
While Iron Heart’s Ultra Heavy Flannels feature a smooth, brushed surface, the Slubby Heavy Flannels add tactile depth with a 12oz slub-yarn weave. The fabric’s irregular surface is rugged by design, combining visual texture with a hand feel full of character.
All that coarseness on the face is offset by a double-brushed interior that’s super soft and extra warm. Perfect for those who love Iron Heart’s heavy-duty, windproof flannels but want something with added oomph in the weave.
Iron Heart’s Work Overshirt cut is roomier and boxier than their traditional Work Shirt silhouette. The generous body, straight hem, and split gussets make it ideal for layering. Stick with your usual size for a relaxed fit, or size down for a more tailored finish.
