Quite a lot, and it's very well organised. Most models in the Ping cart bag range feature a 14 or 15-way top with full-length dividers, keeping your clubs separated and protecting shafts from tangling during transit. The pocket layout typically includes full-length apparel compartments for your waterproofs and layers, velour-lined valuables pockets for your phone and wallet, and cooler sections to keep drinks fresh during the round.
It's a well-rounded setup that covers pretty much everything you'd want access to on the course!
