flip & tumble 24-7 Reusable Bag, Super Pink/Slate It's patent pending stretchy pouch makes it a cinch to go from bag to ball in seconds flat. The bag is 12"x14"x5" with a 26" strap and the ball is 3 in diameter, about the size of a peach. Made of durable ripstop nylon it has a 35 lb. capacity, so feel free to load it up with a bowling ball or two. A shoulder pad keeps heavy loads feeling light.
