12oz Slubby Heavy Flannel Check Work Overshirt Brown

Iron Heart’s 12oz Slubby Heavy Flannel hits that sweet spot between rugged and cozy. Built from slub-yarn cotton, it has that uneven, textured hand and visual depth you only get from specialty yarns — way more character than a standard flannel. And even with all that grit on the outside, the inside is double-brushed, so the comfort is next-level soft and warm.

Cut as an overshirt, it’s made for real winter layering — toss it over tees, henleys, sweatshirts, whatever. The details feel classic Iron Heart: patch chest pockets with a pen slot, button front, work-ready construction. The silhouette leans looser with a straight hem and split side gussets, echoing their mechanic shirt fit. Go true to size if you want that easy, relaxed overshirt feel; size down if you want it trimmer.
