I use this to store my bats...and on the rare occasion I want to bring most of them instead of just 4-6 to the field, transport them. Holds at least 10 comfortably and I think I've managed 12 putting half in handle down, the rest the other direction. Not much room for anything else, but there is a small pocket big enough for wallet, keys, phone, etc.
