13.5oz Rigid Denim. No. 7 denim gets its color from a plant based ash dye and is reinforced with indigo dyed sashiko thread. Over time, the fade of the indigo dyed sashiko thread contrasts with the sumi dyed denim, creating a personalized aging effect. Living up to its name, Century Denim is extremely durable, built to last a lifetime. 100% Cotton Made In Japan Product Code: KAP-74A
