KOJIMA GENES x SAN FRANCISCO

21OZ EXTRA HEAVY
RIGID SELVEDGE DENIM

SHOP NOW

<< KOJIMA GENES COLLECTION

It is heavy, dense, and tough, born with the concept of the traditional worker's jeans. A special automatic loom Riki-Shokki gives the denim a beautiful uniformity of color. As the denim matures, you will enjoy a fade unique to you. This Extra Heavy denim is very limited and you will rarely find it on the market. ​This special denim is a Compilation of Kojima Artisans' Techniques. We have improved the 21oz denim fabric and are now offering the new version. 

KOJIMA GENES x SF 21oz Extra Heavy Rigid Selvedge Denim is back from our successful Kickstarter campaign.

FABRIC

This super heavy, special "rigid-raw" denim is woven by Riki-Shokki - Power Loom by experienced artisans. It is made from 100% US cotton, rope-dyed indigo warp and white weft.

COMPILATION OF KOJIMA ARTISANS' TECHNIQUES 

THE HIGHEST QUALITY & AFFORDABLE PRICE

There are very few factories that can sew this thick and heavy denim. These limited and preeminent pairs are carefully handcrafted by incredibly skilled artisans of Kojima, Japan with extra care on a Union Special Machine. 

KOJIMA GENES works with a new mindset to branch off from traditional ways, cutting out middle agents to keep the costs as low as possible to deliver you the highest quality jeans at the most affordable price point.
