HATTRICK and Hokkaido Yellow Stars Collaborate for Sustainability

In an innovative move towards sustainability, HATTRICK Auction, managed by Valuence Japan Co.,Ltd., will launch the Hokkaido Yellow Stars UPCYCLE AUCTION starting from December 5, 2025. This initiative not only showcases the spirit of upcycling but also highlights the potential for athletes to contribute to environmental conservation.

The Hokkaido Yellow Stars, a professional volleyball team based in Sapporo, competes in the V.LEAGUE MEN East Conference, and has proudly participated in this year's competition, continuing to chase their mission to rise to the top tier, the Daito Life SV.LEAGUE. The upcoming auction will feature meticulously crafted shoulder bags made from repurposed uniform pants used in the 2024-25 season. This marks the second edition of the project, following last year's successful launch.

These bags embody more than just functional fashion; they serve as a testament to how discarded sportswear can be transformed into valuable products, reducing waste and promoting a circular economy within the community. By assigning new value to textile waste, HATTRICK aims to engage fans and the local community in dialogues surrounding sustainability and social responsibility.
