5400-SUMI - Slub Yarn Sweatshirt - Sumi Ink

The 5400-SUMI Sweatshirt from Pure Blue Japan is a modern classic built on heritage craftsmanship. This piece is knit from slub-rich cotton yarns that create an intentionally uneven, tactile surface full of texture and visual life. The fabric is dyed with traditional Sumi ink-based methods, giving it a profoundly deep charcoal tone with subtle tonal shifts that become more expressive with time. Cut in a comfortable, boxy sweatshirt silhouette, it features a crew neck, drop shoulders, and ribbed cuffs and hem that feel properly substantial without being heavy. It’s the kind of sweatshirt that wears in beautifully - softening through the body while its sumi dye reserves just enough character to stand out.

Fit Notes: Shop owner Tommy is wearing a size 5 in this sweatshirt. That is the size he decided to go with on all the tops this round. As you can see by the size charts, these run pretty trim. He would have been able to wear a size 4 in this piece for a more tailored look, but preferred the room of a 5 for a boxier look. We recommend starting with one size larger than what you normally wear. Tommy is 5'10,' 162lbs with a 40" chest.
