The water bottle pockets fit up to 32 oz drinks, with the additional elastic straps, they can also be used to hold bats when not used for bottles, allowing the bag to carry 2 to 4 bats depending on your needs. The front bungee cord is for airing out sweaty items such as gloves or clothes after a game. A zip pocket keeps personal items separate from equipment. 2 D-rings allow for clipping keys or other small items. The sides, back, and bottom of this bag are reinforced to prevent the foam from shifting. Whether for daily practice or a tournament trip, this bag handles it all with ease.
