Edwin's Japanese Rainbow Selvedge Denim weighs in at 13.5oz, and is custom woven by Kaihara Mills in Japan on vintage machinery, woven at a low speed and tension to create truly vintage selvedge denim. A mixture of American and Australian long-staple cotton are used for a softer hand, with the additional benefit of the stark white colour of these cottons allowing a deeper indigo dye to occur. The warp and weft threads are spun differently for traditional texture, with the warp featuring natural middle-pitched uneven yarns to allow 1940's/50's esque fading on the warp, while the weft incorporates shorter-pitched uneven yarns, twisted tightly for a crunchier weave. 

This washed black is named "sumikuro" after the traditional Japanese sumi dye. In Japan, the kanji for "sumi" represents depth and richness, while "kuro" simply means "black." The deep, rich colour of Sumikuro evokes the inky shades of black sumi ink in a package of supremely well made Japanese denim that will hold up for years to come, while also offering some shades of black that are seldom seen within the selvedge denim world.
