Zsig's Ball Carrier is as handy a way for coaches to store and transport tennis balls as you'll find.

No ordinary ball bucket, this. Look at these features:

• Holds 120 standard sized tennis balls
• Holds 96 SLOcoach Big Red (70mm)
• Folds into a flat pack - even the lid - and zips away into a laptop-sized bag with carry handle
• Is in waterproof black nylon
• Has a comfortable shoulder strap

And here's the really great part.

When you've finished feeding balls and are courtside watching play, it's also rigid enough to use as a comfortable seat.
