The CS-100x utilizes 3sixteen's flagship 100x raw indigo selvedge denim that they've featured for over 15 years which is custom woven exclusively for them by Kuroki Mills. The fabric has an extremely soft hand on the inside that is uncharacteristic of raw denim, making it very easy to break in. The CS (Classic Straight) cut is based off a vintage 1947 501 fit and features a straight back yoke that results in a higher rise. The jean has a fuller thigh than their other fits and has a slight taper to the leg opening. The jean is finished with a tan roughout patch, gunmetal YKK hardware and selvedge fly and coin pocket detailing.
