Y-3 is a groundbreaking collaboration between German sportswear giant adidas and legendary Japanese fashion designer Yohji Yamamoto, launched in 2003. The name represents 'Y' for Yohji Yamamoto and '3' for adidas' Three Stripes logo. This partnership was revolutionary for its time, establishing the category of fashion sportswear long before athleisure became mainstream. Y-3 combines Yamamoto's signature avant-garde aesthetic and masterful tailoring with adidas' technical expertise and performance innovation. The brand is characterized by oversized silhouettes, minimal branding, monochromatic color palettes, and sophisticated urban styling. After Yamamoto felt disconnected from street fashion and Nike rejected his collaboration proposal, adidas embraced his vision, giving him full creative control. The result is a modern uniform for the streets that bridges high fashion and sportswear, creating progressive apparel, footwear, and accessories that redefine contemporary style boundaries.
