Room enough to carry two rackets in the side pouch. The bag isn't bulky and still has a lot of usable space that is easy to get to. A water bottle fits easily in a side pocket and a can of balls in the other pocket. The front pockets are useful for tennis schedule, phone, wallet and the large space in the center easily holds a change of cloths and extra shoes AND a purse. I typically carry this onto the court and then to the locker room and forget about putting my change of cloths in the locker. I also used this bag as one of my two carry-on bags for a recent flight and put my iPod and laptop in the pockets as well as my purse, water bottle, change of clots, medication, jewelry, camera and still had room for a snack (and it fit nicely under the seat in front of me! LOVE the bag for tennis and for other adventures with the kids and family!
