These classic work pants, crafted from durable 21oz Japanese serge, blend functionality and style. The heavy cotton twill is designed to fade beautifully over time, showcasing high-contrast shades of grey. With a relaxed fit and thoughtful engineering—including reinforced belt loops and high-strength stitching—these pants are an investment in quality and comfort. Ideal for those seeking a timeless look that pairs well with various casual outfits, they epitomize practical fashion.
From the brand: Our classic work pants, constructed from a hard-wearing 21oz Japanese serge. A heavy cotton twill similar to denim, this is the same fabric as our 21oz Wabash (just without the bleached dots), woven with highly saturated black sulphur-dyed yarns which will gradually fade to high-contrast shades of grey with wear. Cut to offer an unrestrictive, relaxed fit, our work pants exemplify the over-engineering that Iron Heart is renowned for - featuring reinforced belt loops, heavy twill cotton pocket bags and high-strength poly/cotton stitching.
