Century Denim is a line of fabric introduced by Kapital in 2012 as a way to push the boundaries even further.

Kapital employs four factories for the production of their Century Denim, each providing distinct advantages. This entails diverse spinning, dyeing, weaving, and finishing processes, executed with individualised precision for the fabric's benefit. As for the warp, weft, and sashiko threads, these are spun differentially to deliver distinct texture and tension before being separately rope-dyed. Finally, a secretive weaving method exclusively used by Kapital completes the process.

The No.7 finish is a charcoal grey denim which is created through a Sumi Dye process more often used in creating calligraphy ink. This ancient technique uses the soot from flames to make for a black pigment. This combines with the indigo of the sashiko to create a unique finish over time.
