These Sumo sweatpants are made from an ultra-heavy 500gsm 100% cotton brushed fleece—dense, unyielding, and made to outlast. The rich black tone is yarn-dyed using reactive dyes that will soften and fade with time, developing a broken-in character that reflects the miles you’ve put in. While the inside is brushed for comfort, this fleece is all about structure, weight, and serious durability. Finished with a matching 2x1 rib at the waistband and cuffs for reinforcement where it counts. Whether you're putting in work or putting in miles, these are sweats that stay the course.
