Koos Manufacturing has been manufacturing denim products in California for over 25 years and a proud proponate of the Made In U.S.A label.

Established in 1985 by Yul Ku, Koos Manufacturing, Inc. is the premier denim jeans manufacturer in Los Angeles. The only vertically integrated jeans factory on the West Coast, every step from design, cutting, sewing, washing, and finishing are performed in one facility.

In 2000, Yul Ku began exploring a new direction by developing his own brand of jeans in partnership with industry legend Adriano Goldschmied, co-creator of brands like Diesel and Replay. Adriano's design talent coupled with the unique manufacturing experience and capabilities of Koos Manufacturing proved an instant formula for success.
