What Is Selvedge Denim 2 ?

Selvedge Denim (also self-edge or selvage)

Initially known as 'self-edge', the selvedge is the narrow , tightly woven band on both edges of the denim fabric. A selvedge end prevents the edge of the denim from unravelling and shows a clean, finished look.

Old shuttle looms produce denim where selvedges are closed. Alternatively, on larger modern weaving machines, the weft yarn is cut on every pick, resulting in a fringed edge. 

Selvedge and Non-Selvedge

But one may ask, why is selvedge denim so desirable? There are a few reasons for this, one being that the shuttle-loom production process creates a denser weave than non-selvedge. This makes for better quality. Another reason is that the shuttle-loom process is older technology. The same reason someone would want a hand-made wooden table or chair, the character of the traditional method can be seen and felt. The process of the shuttle loom can be slightly inconsistent which leads to variations in the look of the denim which is quite unique for an industry where mass-production and uniformity is the norm. In the world of fast fashion, it is refreshing for some to buy a piece of clothing that will be with them for years to come, gracefully wear and evolve. .

One way to identify selvedge from non-selvedge is what is called the selvedge ID. Selvedge ID color varies with the brand and producer. For instance, colored thread was used by Cone Mills to identify the particular fabric used by it's major manufacturers. Vintage Levi's jeans were originally an all white strip and later had a single red striped selvedge. Lee's had a blue or green strip along one and Wrangler's was yellow. Nowadays, many selvedge denim brands get creative with their selvedge IDs because they know that customers love to show them off. As you can see below, KATO' enjoys this detail of expression.

What is raw denim?

Also known as dry or unwashed denim, raw denim has not gone through any washing or distressing processes as is typical with other jeans. As you wear the jeans, the denim will fade at crease points and mold to your body. This essentially creates a moving art piece that showcases your life and active lifestyle that caused the wear. The longer you go before the first wash, the more prominent fading will be. For this reason, some denim-heads go months or even years before the first wash. Quality raw selvedge is a piece of clothing you don't have to feel strange about wearing nearly every day. In fact, many pride themselves in how fast they can get wear marks on their jeans in the least amount of time, which is done best by wearing them daily and forgoing that first wash for as long as possible.

Why Japanese Selvedge?

At one point in time, most of the world's denim was produced in the United States. As time passed, the quality suffered as mass production took priority over more time intensive traditional methods. So where does Japanese denim come in? In the 1960s, Japan entered into the denim business. Jeans became popularized by observing the denim worn by US soldiers after World War II and became fashionable across Japan. As Japanese craftsmen began producing denim, some decided to stay true to the traditional methods and dedicated themselves to produce higher quality denim than other regions. Japan is one of the only places to stay committed to the vintage shuttle-loom produced denim manufacturing process which is costlier and more time intensive. Today, Japan is considered to produce the best quality denim in the world. Their high quality standards and attention to detail has refueled an appetite across the globe for higher quality jeans.

At our source of the Japanese Mill, there is an intensive process of rope-dying and shuttle-loom weaving taking place. This meticulous process and finished result is what makes Japanese selvedge denim the most sought after in the world. Japanese Mill specializes in sanforized denim, which refers to the pre-shrinking of the fabric to less than 1%. This reduces unwanted size changes. That means if you like the fit when you try on KATO', you most likely will continue liking it as time passes.

What are the origins of 4Way Stretch Selvedge Denim?

Nick, our designer at KATO', took selvedge denim to the next level. He wanted to create a denim which not only looks authentic but also is comfortable. You can find a lot of uncomfortable but great looking denim on the market but he couldn't find the one that had both great style and comfort aspects. He sought that everyday comfort but was unwilling to compromise the vintage elements in the process. After years of working with Japanese Mill with non-stretch selvedge, he wanted to make the transition to an unattempted 4Way stretch. At first, the mill told him that it was technically impossible, but Nick was unwilling to accept defeat. After many failed attempts, they were able to produce this amazing 4Way stretch fabric that is used in all KATO' jeans. 

Everyday someone is making the leap into breaking in their first pair of raw denim or adding another pair to the collection. Our 4Way Stretch Selvedge has the fit, look, details, and comfort that will satisfy everyone from the seasoned "Denim-head" to the conservative customer trying their first pair of raw jeans. Our 4Way Stretch Selvedge Japanese fabric has the perfect amount of 360 degree, multi-directional movement. The jeans will fade like a dream, except they are more comfortable than any other authentic selvedge jeans on the market.
