Kojima Genes has been making jeans in Okayama for 20 years, although they are still not very known in the US. They operate in a small factory where everything is done under one roof and have their flagship shop on Jeans Street in Kojima.

Kojima Genes just launched a crowd funding campaign on Indiegogo to kick off their new San Francisco based brand, Kojima Genes x SF. I am excited to be reviewing one of the two offerings that are available for pre-order through the campaign.

Extra Heavy 21oz Kuroki Selvedge Denim – Limited “Riki-Shokki – Straight Cutimg_5748

Fabric: A very limited 21oz sanforized selvedge from Kuroki mills using a “Riki-Shokki” loom. Made from 100% US cotton. Densely woven with a moderate slub in both the warp and weft, giving it a nice crosshatch pattern. Rope dyed indigo warp and white weft.

First Impressions: I really like the fabric used on these. A very thick and heavy denim with tons of character. There is a very slight red cast to the fabric. Because of the loose cut you can wear these 21oz heavyweights all year round without it getting too hot. The cut is like a slightly looser Levis 501 1947. Great for those with large thighs or those who want a very vintage style cut. One of my favorite details on this pair is the beautiful patch, witch will feature a hand stamped serial number over the top. These are simple and well constructed jeans handmade in Okayama for a great price. img_5981img_5979img_5962img_5988img_5990img_5996img_5945

This pair is currently available for only $159 Kojima Genes x SF Indie GoGo campaign! They also have a very nice 13oz Natural Indigo in a slim cut for $139! Really a great deal you should definitely check out.
