Pure Blue Japan is taking a journey in the denim time machine with their latest release, the XX-013-VTG. If the double X’s and “VTG” moniker didn’t give it away, this is the brands interpretation of what is safely recognized as the most iconic pair of jeans in history, the original Levi’s 501.

They knew that if they were going for authentic, they needed the denim to match, and developed an exclusive 14oz. unsanforized Japanese denim featuring PBJ’s signature super slub, which means a more balanced and tight, even weave like those old jeans you find in your grandparent’s attic.

The least vintage part of this release is the fit, a modest slim taper with a mid rise and narrow leg openings. Other details include a pink selvedge ID, lambskin leather patch, and custom PBJ hardware.

Available for $230 at Okayama Denim.
