Selvedge ID

The selvedge ID began as a purely functional detail—a technique of weaving the edge of a fabric into itself to prevent it from fraying. The word “selvedge” comes from “self-edge”. Over time, mills began color-coding these edges to identify the different fabrics for the brands they supplied. Hence the name “Selvedge ID”. The most iconic ID colors are the red on white and blue on white variations. What started as reinforcement became a signature; that narrow strip of color is now a symbol of authenticity and quality.

Kato introduced our first selvedge denim in 2016: a 10.5oz 4-Way Stretch Selvedge with the classic red line. When we developed our heavier 14oz version, we gave it its own identity—an orange stripe paired with a fine navy line. Every denim fabric we craft has its own unique selvedge ID.

We treat each selvedge ID like a signature—an intentional detail that distinguishes the fabric and reflects the same level of craftsmanship found in every stitch of our jeans. It’s more than just a line at the edge; it’s a quiet statement of who we are and the standard we refuse to compromise.
