A collaboration series by art director and designer Toyoki Adachi with textile graphic brand "nowartt" that incorporates heritage and modern art. This time, the nowartt original pattern, which was inspired by ice crystals, was precisely and faithfully woven using the traditional Japanese textile Kinkasan Ori, resulting in a thick, high-quality material with a good texture. Original fabric is placed on the back of the flap to accent the design. In addition, the outer material is made of high-density nylon twill that is woven with a high density of 210D for the warp thread and 420D for the weft thread, giving it a moderate luster and an elegant look. Made of INVISTA's 630d Cordura® nylon, which has 5 times the friction, tear strength, and durability. By using two different materials of the same color, we have created a design that combines colors like a gradation.
