This 5-inch inseam seamless biker short is developed as a high-rise activewear bottom using ribbed stretch knit construction to deliver controlled compression and shape stability without layered paneling. The integrated front-smoothing zone is engineered through knit density variation rather than added lining, supporting streamlined construction and consistent grading across sizes. Designed for coordinated set development, the structure allows scalable OEM and ODM production for seamless ribbed activewear programs with flexible compression and yarn customization options.
