{"type":"firestarter.listing","listing":{"id":"lst_o9TsCrps","product_name":"CS-220x ~ Classic Straight - Double Black","category":"Denim","description":"The CS-220x jean features a classic straight fit paired with beautiful custom Japanese raw double black selvedge denim and American construction. The CS (Classic Straight) cut is a true straight leg fit featuring a mid-high rise, room in the hip and thigh with a slight taper from the knee down - loosely modeled after the 1947 501. \nThe CS-220x utilizes our flagship 14.5oz raw double black selvedge denim that has been custom woven exclusively for us by Kuroki Mills for over 15 years. The fabric has an extremely soft hand on the inside that is uncharacteristic of raw denim, making it very easy to break in. \n  \nDouble black selvedge is what we call black warp/black weft denim, yielding a deep black color that will fade to grey in areas of high wear with time. \n  The CS jean is loved by our widest range of customers: it’s a versatile straight leg silhouette that can be worn casually or dressed up, coupled with heritage-driven fabrics that will last a lifetime.\nThoughtfully designed for daily use, long-term wear, and gradual evolution throughout.\n!split!\n!details!\n\n100% cotton 14.5oz raw double black selvedge denim\nWoven in Okayama, Japan by Kuroki Mills exclusively for 3sixteen\nSanforized, skewed and lightly singed - minimal shrinkage\n\nSelvedge fly and coin pocket detailing\nTrademark back pocket stitch overrun\nBlack roughout leather patch\nMade in USA\n","images":["https://cdn.shopify.com/s/files/1/0028/6132/products/20230110-3sixteen-pants-black-01.jpg?v=1673489881","https://cdn.shopify.com/s/files/1/0028/6132/products/20230110-3sixteen-pants-black-02.jpg?v=1673489882","https://cdn.shopify.com/s/files/1/0028/6132/products/20230110-3sixteen-pants-black-03.jpg?v=1673489881","https://cdn.shopify.com/s/files/1/0028/6132/products/20230110-3sixteen-pants-black-04.jpg?v=1673489881","https://cdn.shopify.com/s/files/1/0028/6132/products/CS-220x-Front-close.jpg?v=1673490163","https://cdn.shopify.com/s/files/1/0028/6132/products/220x-Selvedge.jpg?v=1673490163"],"price":270,"currency":"USD","in_stock":true,"inventory_qty":109989,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:18.393Z"},"share_url":"https://firestarter.network/l/lst_o9TsCrps","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
