  • Product with ethical values.
Our belt is made of the finest 100% organic cotton canvas textile, and its colour is achieved through advanced dyeing techniques, using exclusively natural dyestuffs. By incorporating the robust, flat 4-layered structure inspired by traditional Japanese judo belts, we’ve added a touch of modern sports design with the use of a high-quality aluminium COBRA® buckle made by AUSTRIALPIN, a renowned manufacturer of mountaineering and sky sport equipment.

Available in 2 materials / 3 colours, including a model with reflective (retroreflective) fabric on its entire surface.

[ Due to the size of COBRA® buckle, the inner circle of the trousers’ belt loop needs to be more than 10cm.]


The finest quality canvas fabric, which brings a pleasant texture unique to cotton, is an ESC original textile created through the excellent craftsmanship of a canvas maker in Shiga Prefecture. This maker has inherited and preserved the traditional Takashima sailcloth quality for generations. Only natural-origin materials, including pigments are used throughout the entire process. Compared to conventional belts made from leather or petroleum-derived materials, this 100% organic cotton belt is an ethical choice for both the human body and environment. It is woven with unbleached yarns to enhance the comfortably rich texture and colour of the high-quality cotton. Additionally, one of the notable features of the cotton canvas is its ability to change in texture over time and with use.

【Natural dyeing】

Our focus was on harnessing the rich colours of traditional Japanese mineral dyeing, an ancient technique believed to enhance the suppleness of the thread, as well as offering insect-repellent and deodorising properties.
The unique iron powder dyeing procedure was meticulously carried out by skilled dyeing artisans at a renowned studio in Tokyo, using upcycled iron powder sourced from shipbuilders in the Hiroshima-prefecture. This mineral dye evokes the authentic colour and texture of iron itself. The natural changes in both the colour and texture are to be enjoyed, much like with indigo-dyed denim garments.

[ Due to the nature of the dye, changes in texture and gradual colour fading are to be expected as a result of friction over time.]


This garment features a top-®️ buckle made from aluminium by AUSTRIALPIN, a renowned Austrian manufacturer of mountaineering and sky sport equipment. For safety, the buckles are designed to only be unlocked when both clips are pressed at the same time (load capacity: 9KN). Manufactured in Austria by skilled artisans.

【Metal emblem】

The ESC logo features the brand's iconic elephant by fusing the design elements of a traditional Japanese family crest with contemporary graphic features. The brass badges are forged with expert craftsmanship in a workshop located in downtown Tokyo, a historic production area renowned for creating the finest insignia emblems.
