12oz Ultra Heavy Flannel Work Overshirt IHSH-452-CAM – Overdyed Camel

The Iron Heart IHSH-452-CAM is a 12oz Japanese Ultra Heavy Flannel (UHF) work overshirt, introduced for Fall/Winter 2026 in a rich overdyed camel colour. Made from 100% Aspero cotton, the heavyweight twill fabric is double brushed on the inside and single brushed on the outside, creating the warmth, softness and substantial feel that Iron Heart's Ultra Heavy Flannels are known for.

Unlike the traditional checked UHF shirts, this edition features a solid camel-brown colour achieved through overdyeing after construction, adding depth to the fabric and an even softer hand feel. Cut with a relaxed, oversized fit, straight hem and practical chest pockets, it works naturally as a heavyweight shirt or an outer layer over a T-shirt or sweatshirt.
