Garment details
Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.
Samurai's Heavyweight T-shirts are crafted using thick slub yarn, and sewn with the same level of expertise as the brand's denim. This special collaborative installment pairs with the Shizen Selvedge Denim by using the same set of natural dyes. This iteration is dyed using traditional susuzome sumi ink, commonly used in calligraphy, resulting in a deep charcoal-black color that highlights the cotton’s natural slub variation. Crafted in Wakayama, Japan, the shirt is knit on circular machines and sewn with natural cotton thread. Woven using natural slubby cotton, the shirt is finished on a 1960's vintage Union Special for an authentic vintage feel.
