Iron Heart designed this season’s plaids to offer a sort of “greatest hits”, inspired by some of Iron Heart 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), Iron Heart SS26 shirts are among the most distinctive Japanese-made flannels available this season!
So Guys, don’t wait too long if you want to grab one of these great summer flannels!
