All zippers are METAL in perfect working order. I would say it is equvilent to a 10/12 pack. Lotsa of room in a very nice bag. This is a heavy duty Quality bag with a sturdy shoulder strap and handles, Metal D- rings for superb support. They don't make them this way any more. the Bag is Red with a Black underside and Volkl is printed in Bold Black letters on both sides. Perfect for going to weekend tournaments or that trip to the sectionals ! Also large enough for your work clothes and shoes for the afterwork match/league.Two zippers on top with a valcro strap between, which allows a large entry without obstruction into the bag. It has Side pockets, and a Wet compartment underneath.
