IHSH-189-BRN - 17oz Duck CPO Work Shirt "The Untucked" - Brown

“The UnTucked” is exactly what it sounds like, a CPO work shirt cut with a slightly shorter, balanced length so it sits clean when worn untucked. First introduced in 2017, this design blends the silhouette and patch chest pockets of a traditional work shirt with the oversized copper snaps and handwarmer pockets pulled from classic CPO styling.

Built from 17oz Japanese cotton duck, this is dense, plain-weave canvas with real backbone. The brown warp and weft give it depth from day one, and the fabric will gradually fade and soften with wear. Sanforized and one-washed, it is ready to go with virtually no shrinkage expected. Twill-lined collar and cuffs, bias-bound arm openings, chainstitched side seams, and felled internal seams round it out with serious construction throughout.

Designed by Shinichi Haraki and handmade by WORKS INC. in Japan, this is a hardwearing overshirt that only improves the more you put it through.

Fit Notes: Tommy wears an XL in almost all shirting from Iron Heart. This one has bit of an outerwear touch, so it runs roomier. He could wear a large, but preferred the XL. We recommend you stick with what you normally buy from Iron Heart, in terms of shirting. Tommy is 5'9," 165lbs with a 40" chest.
