T-League and Tamas Corporation, better known by its brand name, Butterfly, are teaming up with JEPLAN, Inc., the force behind the eco-friendly initiative, BRING. The three entities are setting the stage for a more sustainable future with their joint project, “WEAR RALLY PROJECT 2023.”

BRING, with its long-standing commitment to sustainability, has been a major player in collecting and recycling unwanted clothing. This latest venture sees the organization collecting cherished clothing memories and old garments from fans at T-League match venues. But the effort doesn’t stop at mere collection.
An interesting twist to the initiative is JEPLAN’s innovative approach to recycling. Clothes made from 100% polyester are given new life using the company’s proprietary technology. This technique transforms them into a regenerated polyester raw material, aptly named “BRING Material,” which then becomes the foundation for new clothing items.
One of the highlights of this collaboration is the production of the “T-League Connect T-shirt.” Not only does this shirt emphasize sustainability by utilizing “BLANK APPAREL,” which incorporates some of the regenerated polyester material, but fans also have something to look forward to. This unique T-shirt will be presented in limited quantities at the Nojima T-League Playoffs in March 2024, turning eco-consciousness into a tangible reward for sports enthusiasts.
