The Spalding NEVERFLAT Basketball is the first ever ball with Pressure Retention Technologies and is the only ball guaranteed to stay fully inflated for at least 1 year – 10x longer than any traditional basketball. The NeverFlat basketball houses an exclusive membrane technology that tightens the natural pores in the bladder to improve pressure retention along with a valve cap that eliminates leaks and keeps dirt out. Additionally, we use a proprietary technology called Nitro-Flate which is injected into the ball forming a protective barrier against air seepage.
