Offering a lighter weight alternative to our signature Ultra Heavy Flannel (UHF) shirts, our 9oz selvedge unbrushed flannels provide classic Iron Heart styling in a cooler, more breathable option for the warmer months.

We’ve designed this season’s plaids to offer a sort of “greatest hits”, inspired by some of our most popular UHF colourways from over the years. Unlike previous 9oz flannels — which were rope- and sulphur-dyed to allow for fading — these fabrics are woven with more reactive-dyed yarns for a more colourfast finish. With only four shuttle looms in Japan capable of producing these intricate patterns (which require switching the weft yarn mid-weave), our SS26 shirts are among the most distinctive Japanese-made flannels available this season.

This model features our regular fit work shirt cut, complete with white 4-hole button fastenings, in a classic sax blue check — reminiscent of our sought-after 20th anniversary UHF from 2022.
