Decided to purchase a 6-pack because I prefer to have additional compartments. It looked very saggy with 2 racquets and misc equipments inside. What did I do? Ghettoed rig the bag with free e.bay boxes! I traced the shape of the front/rear pockets onto a cardboard. After test and error, I replicate the original piece and triple layered it for better support. Before: Cardboard inserts: After: Looks much better than before.
