IRON HEART 634S-BK 21oz Black Selvedge Straight Jeans
Product Overview
The IRON HEART 634S-BK is a black-denim version of the brand's long-running 634S straight model. Built from IRON HEART original 21oz selvedge denim, it is woven slowly on shuttle looms using intentionally thick yarns to create a dense, tough fabric with a distinctive texture.
The 634 straight fit is designed to keep a clean line while reducing excess bulk often found in selvedge jeans. Construction focuses on long-term durability, combining vintage-style stitching techniques and reinforced hardware for years of wear.
This black denim uses sulfur dye similar to traditional indigo dyeing. With wear, whiskers and creases will appear and the color will gradually fade from black toward gray, creating a unique aging pattern.
