Japanese factory brand creating playful, luxury knitwear from high-quality deadstock yarns.
ORIGIN
Japan
Founded in 2005 by designer Hiroki Wakisaka, Side Slope is a Japanese knitwear label that originated as a factory brand with a unique sustainable mission: to repurpose the tons of deadstock yarn left over from mass production. Leveraging the technical expertise of its parent company, UP HILL Co., Ltd., the brand transforms these high-quality surplus materials into sophisticated, playful knitwear for adults. Wakisaka, a veteran knit designer, established the brand to elevate the status of factory craftsmanship while addressing industry waste.
