Spalding has improved upon the original basketball design to bring you Never Flat technology. By reinforcing the bladder with special materials and using a cap seal, Spalding guarantees this basketball will be inflated for at least 1 year of use for the first year of use. That is up to 10 times as long as the traditional basketball design. The composite leather feel to the basketball provides great handling and long lasting grip. This basketball is meant for outdoor use.
