Orobor is pioneering a new era of circularity in sports and fashion—turning tennis string waste into high-quality, traceable materials that power a cleaner, more transparent future.
At Orobor, we believe the game is bigger when everyone has the chance to play. That's why for every adult tee purchased, we donate a kids' tee to a young player who needs it most.
Through One for the Court, we work with nonprofit organizations around the world that use tennis to empower kids in underprivileged communities. Your purchase helps put apparel directly into the hands of the next generation, giving them the confidence and sense of belonging that comes with stepping onto the court.
Every shirt is more than apparel — it's an opportunity to grow the game and extend its reach to places where it can have the greatest impact. Together, we are giving back to the sport that has given us so much.
Our commitment to reducing environmental harm through innovative recycling
Incinerating tennis strings releases approximately 2.5 kg of CO₂ per kg of polyester, along with toxic pollutants, into the atmosphere.
Reduce CO₂ emissions from virgin polyester by 50%, helping to combat climate change and its impacts on weather, sea levels, and ecosystems.
Prevent billions of microplastics from tennis strings entering our waterways, damaging marine ecosystems and entering the food chain.
Orobor, founded by tennis players at Boston University, Our mission is to create more than apparel. We create stories of transformation where wast is reimagined, performance is redefinded, and community is built. We aim to inspire sustainable practices across industries—all while staying rooted in the values of teamwork and dedication we've learned on the court.
