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.

It would appear as though this work shirt is cut slighter slimmer in the same XXL size as the westerns. I’ll be sure to get with the IH crew on order day to sort it out👍. Super stoked,

Hence, the more muted colours. See here

I hope I didn’t mixed up things.

Perhaps the flannel with be a tad brighter, especially with the blue?
