21oz Denim Straight Cut Jeans - Black

Made from our super heavy projectile loom woven 21oz black Japanese denim, these classic straight cut jeans are Haraki sans first jean design for Iron Heart. The non-selvedge outer seam allows these jeans to be a little more tapered in the larger sizes, creating a slightly narrower leg opening then our regular 634 cut.
