Most traditional high-end sports balls are made with a polyurethane or synthetic leather outer shell and a rubber air bladder. Aggressive harvesting of rubber can deplete forests. Fair Trade Sports in Seattle makes high-end sports balls out of FSC-certified rubber, which means the rubber comes from a responsibly managed forest. Fair Trade Sports makes earth-friendly soccer balls, volleyballs, futsal balls, rugby balls, footballs — and soon basketballs. The company’s professional-quality balls are priced competitively with those from the big-name companies. Mid-range balls for competitive play cost from about $30 to $60.
