Pure Blue Japan XX-019-18oz-IDBK Denims (Relaxed Tapered Fit)

We’ve brought in those 'Heavy Ounces’ with a Deep Grand Indigo X Black Sulphur Indigo denim.

The 019 fit comes with a relaxed waist, roomy thigh section and an extra tapered leg opening.

This 18oz denim is dyed with a deep grand indigo for the warp and a black sulphur indigo for the weft. The overall look is super dark and has that strong stubbly texture we know and love!

With time the denim will turn to a vibrant, light indigo look with some amazing highlights and enhanced slubby texture.

As for the hardware, each component has been black coated and will eventually reveal a shiny, iron core with time.

If you’re after a pair of black denims with indigo soul? This is it!
