This 13.0oz denim shirt is woven with Kakishibu-dyed thread in the warp. Kakishibu dyeing, also known as "sun-dyeing," involves exposure to sunlight and air, which causes oxidation and changes the color over time to a deeper hue. The most appealing aspect of this dyeing method is that the color evolves as the fabric is worn, allowing for a unique patina to develop. With each wear, the texture deepens, creating a one-of-a-kind finish. The natural unevenness created by the use of natural dyes gives this denim shirt a warm, distinctive feel. Additionally, the nut buttons add a natural texture, complementing the simple yet profound design of the shirt.
