One Piece of Rock relies on the skills of master craftsmen in Japan’s denim mecca, Kojima, Okayama. Under the direction of Yoshiaki Konaka, a vintage clothing aficionado, the brand aims to achieve an authenticity to the original whilst offering something for today’s denim market.

The S409XX jeans and S406XX jacket place emphasis on the wartime manufacturing policies and production methods enacted by governments during times of hardship. During World War II, this had a significant impact on the manufacture of denim and dictated what materials shouldn’t be used, where shortcuts could be made and efficiencies introduced. Both garments utilize a 13.5oz. selvedge denim woven by the revered looms of Okayama. The fabric weight is textbook of the World War II era, as a result of the rationing of raw materials.

The S409XX showcases the simplicity and beauty of wartime production. The jeans feature a button fly with laurel wreath buttons, no rivet on the coin pocket, a lack of bar tacking on the back pockets, uneven pocket position and even a selvedge seam which is not fully open (a result of prioritizing production speed during wartime economy). The S406XX features similar details but also sees the left chest pocket flap removed, as done on the originals. It is also worth noting that due to the construction of the fabric, these pieces will achieve true vintage fading and color, so sought after by denimheads the world over.
