IHSH-412-YEL - 9oz Selvedge Indigo Check Flannel Work Shirt - Yellow

$ 385.00

Iron Heart’s 9oz selvedge unbrushed flannel western shirt in yellow offers a lighter-weight alternative to the brand’s signature Ultra Heavy Flannel (UHF) shirts, providing classic styling in a more breathable fabric suited for warmer months. This season’s version features a timeless check pattern in a yellow-based colorway, woven slowly to enhance texture and weight. The darkest yarns are indigo-dyed, while the lighter shades are sulfur cheese-dyed, allowing for natural fading over time. With only four shuttle looms in Japan capable of producing this intricate pattern—requiring the weft yarn to be switched mid-weave—this SS25 release stands out as one of the most unique Japanese-made flannels of the season.

Fit Notes: Tommy is wearing an XL in the pictures for that roomier work shirt vibe. That has been his standard size in almost all shirts and fits just the way he likes - roomy without looking sloppy. We recommend you size up at least once in all shirts from Iron Heart. Tommy is 5'10," 165lbs with a 40" chest.
