Premium Jeans Manufacturing in Los Angeles

Founded in 1985 by Yul Ku, a visionary in denim manufacturing, Koos Manufacturing built a legacy of craftsmanship through collaborations with brands such as Calvin Klein, Abercrombie, Gap, and Ralph Lauren. These partnerships quickly established Koos as one of the first premium denim producers on the West Coast. Located in Los Angeles, CA, the company operates as a fully vertically integrated facility, overseeing every stage of production under one roof.

In 2001, Koos Manufacturing began producing denim for AG Jeans, a brand that goes beyond trend-driven fashion to prioritize quality and sustainability. Koos has been at the forefront of environmentally conscious denim production, incorporating Ozone technology, laser finishing, heat recovery, solar energy, and advanced water saving techniques. Koos commitment to sustainable practices continues to set a new standard for responsible denim design.
