NBA All-World Gear features an upgrade system that means Gear isn't just aesthetic, it's also functional. The upgrade system gives you the opportunity to increase the boosted values of the Gear you equip your Players with.
When you find Gear for the first time, you can accessorize your Player with it. Some Gear adds +1 stats in each category. As you travel to Drop Zones, you'll find more chances to collect more pieces of Gear. You can increase that +1 all the way up to +5. Have fun traveling to collect all that Gear!
