Wilson Ultra USPTA High Altitude 12 Cans
Play on any surface for longer! Wilson Ultra USPTA High Altitude All Court Tennis Balls feature a thicker, tighter-woven high-visibility felt that increases durability and ball tracking. These tennis balls were designed for use on all courts with an elevation above 3,500 feet in. Wilson also uses a new application process for their logo, resulting in a longer-lasting wear period.
