The question is impossible to answer because Mission Balls are used on a wide variety of surfaces in many different countries. Obviously the ball life will change if used by children on nice grass or adults on tough gravel. We are very purposeful about each aspect of the construction of The Mission Ball. From the bladder, to the stitching, cotton blend for strength, and PVC leather for durability. The Mission Ball is NOT a cheap throw away product. Each ball has been inflated and tested for air retention before we ever receive it. We can confidently say The Mission Ball will hold up as good, if not better than most other soccer balls out there. Of course there are certain times / areas / situations where no ball could withstand the abuse and environment. We use a butyl bladder for longer air retention, cotton underlay for strength, and PVC leather for toughness.
