The first model in the ANATOMICA jeans collection. The 618 Original, with its beautiful silhouette reminiscent of the golden ratio (1:1.618), is the model that connected director Pierre Fournier and designer Kinji Teramoto, and is the first pair of jeans from the ANATOMICA brand, a true masterpiece. Inspired by US NAVY work pants, it features a seamless construction with no side seams. When rolled up, there's a unique detail: the selvedge isn't in the usual place. It has a classic impression with a high-rise, straight silhouette. This pair of jeans uses 16oz left-hand twill indigo fabric, specially developed for it. Left-hand twill denim is a special fabric used in 1950s American denim. It's a unique pair with specifications exclusive to ANATOMICA. 【Material】COTTON 100% 【Made in】Japan Size 31
