Relaxed fit sweatpants in middle-weight French terry. Features a custom dye treatment. Belted nylon waistband with magnetic closure at the front. Elasticated cuff at the hem. Made in Japan. Marble Mix combines processes from our Carnival and Marble programs. Produced start to finish in Kojima, Japan, each piece is first treated with an all-over marbled finish. Then, they're folded like origami and randomly dipped by hand in a proprietary solution that separates multiple colors of dye, similar to the effect of oil in water. This labor intensive process ensures every garment is completely unique. 100% Cotton.
