IH-731-KHA - 12oz Heavy Cotton Relaxed Fit Chinos - Khaki

$ 330.00

Iron Heart’s IH-731-KHA is a heavyweight chino that redefines what casual trousers can be. Built around a sturdy 12 oz Japanese cotton twill, these are cut with a relaxed fit and medium rise to offer both durability and everyday ease of wear. Features include a zip fly with a secure hook closure, two twill-lined rear pockets (one with a button), and a non-selvedge, reactive-dyed fabric designed to retain its rich khaki tone without fading over time. Designed by Shinichi Haraki and meticulously crafted by Works Inc. in Japan, this chino is one of those rare pieces that’s as functional as it is refined - aging well while keeping its structure.

  • 12 oz heavyweight Japanese cotton chino cloth (twill weave)
  • Relaxed fit with medium rise
  • Reactive-dyed warp & weft for fade-resistant color
  • Zip fly with hook-and-eye closure
  • Two twill-lined rear pockets (one buttoned)
  • Four-pocket design plus coin pouch
  • Non-selvedge construction
  • One-washed to eliminate shrinkage
  • Made in Japan

Fit Notes: Shop owner Tommy is wearing a size 35 in these. He has decided to size up even once more to get the fit he wants in the leg. While the waist is a little roomier than most would want, it's what he prefers to get his best fit. We would recommend sizing up at least once in these if you don't know your size. Tommy is 5'10", 160lbs with a 33-34" true waist.

*These chinos are cut with a relaxed top block, medium rise, and straight leg that tapers slightly at the hem for a clean but comfortable silhouette.*
