This sweatshirt is built from a tightly knit 14.5oz fabric made using open-end, air-spun yarn that delivers a dry, firm hand with real structure. The yarn is rope-dyed in indigo, then overdyed with kakishibu, a traditional persimmon tannin dye that has been used in Japanese clothing since the Heian period. The result is a deeply layered color that continues to darken and evolve with wear, with natural variation that reflects the character of the dye itself. Samurai carries this same yarn through the ribbing for consistency, and finishes the garment using a 4-needle flat seamer, adjusting the cutting blade so hints of the kakishibu tone appear at the surface. It’s a sweatshirt that feels historically rooted, technically obsessive, and quietly special from every angle. 14.5oz Japanese knit fabric 100% cotton 30-count open-end air-spun yarn Indigo rope-dyed yarn overdyed with kakishibu persimmon tannin Dry, firm texture with moderate air content Matching ribbing made from the same yarn 4-needle flat seamer construction Visible kakishibu tone at cut edges Natural dye process with inherent color variation Made in Japan table { width: 100%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: center; } th { background-color: #f2f2f2; } Tag Size Chest Shoulder Back Length Sleeve S 20.9 17.9 24.0 23.4 M 21.7 18.1 24.4 23.8 L 22.0 19.3 25.2 24.4 XL 22.4 19.3 28.0 25.6 XXL 23.6 20.9 28.3 26.0 XXXL 24.4 21.3 29.1 26.6 A variance of +/-.5" is within tolerance.  Fit Notes: Tommy is wearing a size Large in this piece.
