You know what they always say about the wicked… they don’t rest. In this case “the wicked” is referring to the indigo powerhouse Iron Heart and their non-stop production of high quality and famously hardy clothing, like this new Indigo-Dyed 10oz. Selvedge Flannel Shirt.

Indigo dyed? Check. Selvedge? Check. 10oz of pure heavy duty cotton flannel? You guessed it… Check. Iron Heart is pulling out all the stops on this one, sourcing this beastly un-brushed fabric from a small-scale house mill that made the material using yarn that was dyed with true indigo. And that means it’ll fade just like your favorite jeans over time. This shirt also features metal cat’s eye buttons, double chain-stitched felled seams with run-off, and is being sold as a single wash to take out just about all of the initial shrinkage. What more can you ask for?

Available for $310 at Self Edge.
