9oz Selvedge Flannel Check Work Shirt Orange

A lighter weight version of Iron Heart’s iconic flannels, made for warmer weather but still packed with the texture and durability that make IH shirting so addictive. These 9oz selvedge unbrushed flannels offer a cooler, more breathable feel than the Ultra Heavy Flannels while keeping that same rugged character.

For SS26, Iron Heart pulled inspiration from some of their most loved plaid colorways from past seasons — a greatest hits run through the UHF archive. This bold orange check calls back to the popular IHSH-399-ORA from FW24, bringing that punchy vintage workwear energy into a lighter fabric for spring and summer.

Unlike earlier 9oz flannels designed to fade over time, these are woven with reactive-dyed yarns for a richer, more colorfast finish that keeps the pattern looking sharp wear after wear. The fabric itself is woven on rare Japanese shuttle looms capable of switching weft yarns mid-weave to create these intricate plaids — a process only a handful of looms in Japan can handle.

Finished in Iron Heart’s regular fit work shirt cut with white 4-hole buttons throughout. An easy everyday flannel with enough color and texture to stand on its own.
