- The Boncoura 41 Indigo Trousers draw from the classic military “41 Khaki,” reworked here in a custom indigo herringbone twill. The familiar silhouette remains, but the fabric brings a different kind of depth and character.
Made from carefully selected raw cotton and spun into custom indigo yarn, the herringbone twill uses indigo in both the warp and weft. This gives the fabric a deep, layered tone, with the pattern gradually becoming more visible as it fades - developing a clear, high-contrast expression over time.
While staying true to the original military details, the silhouette is refined with a natural curve through the leg and a clean taper. The construction reflects the same level of attention, with original hardware, belt loops integrated into the waistband construction, and durable double-stitched seams throughout. For those who appreciate the character of indigo and a more refined silhouette, it’s the kind of pair that settles in and becomes more personal over time.
