IHSH-423-CAM - 13oz Oxford Cloth Work Overshirt - Camel

New for Fall/Winter ’25, the 13oz Oxford Work Overshirt is cut from a heavyweight Japanese Oxford cloth designed for everyday durability and comfort. The fabric is woven with double warp and weft yarns in a dense plain weave, creating a thick, tactile surface with a soft hand and substantial structure. At 13oz, it’s one of the heaviest Oxford fabrics we’ve handled - robust yet breathable, making it ideal for layering through the colder months. The material is reactive-dyed for long-lasting, fade-resistant color and finished with tonal stitching and buttons for a clean, understated look.

Designed by Shinichi Haraki and handmade by WORKS INC. in Japan, this overshirt bridges traditional workwear function with refined modern tailoring. The cut features a straight hem, side-seam gussets, and a slightly looser silhouette than the brand’s standard work shirt, making it perfect as an outer or mid-layer. The dual chest pockets include a pen holder for utility, while the reinforced stitching and chainstitched side seams showcase true workwear construction.

Fit Notes: Tommy is wearing an XL in this piece. He rarely, if ever, says this, but he could wear a size smaller in this. The Overshirt is one of the first shirts to ever carry a boxy fit, so this makes sense. We would recommend buying your true size in this garment, which might be one size smaller than what you normally wear from Iron Heart. Tommy is 5'10," 162lbs with a 40" chest.
