LOTS of room! BUT...grey color is not as pictured. A little dissappointed as the grey color I thought I ordered showed up as charcoal grey accents instead of silver grey as pictured. Not a bad color, just not what I ordered (see pics), resulting in the 4 star rating. Other than that, a great bag. Sorry, Amazon only loads pics in landscape but I took pics in portrait, hence the sideways pics. Anyway, the main compartment is HUGE. Will fit all of your clothes, balls, waterbottle, etc, There's a separate zippered shoe compartment at the bottom that shares room in the main compartment. Finally, there are 4 other small zippered compartments on the sides. Top left is fleece lined for you sunglasses. Bottom right is an insulated foil lined compartment for a small snack, juice box or 12 oz soda. The last 2 are regular nylon lined for your keys, etc. Almost forgot the racquet compartments. After all, this IS a tennis bag. As pictured from Amazon, there are 2 zippered pouches for racquets with a unique "samurai sword" style storage. A cool feature so your head does not hit your racquet handle(s)...especially if you ride a bicycle to the courts. Bring back the silver and black!

Looks like Amazon changed the product picture. Good for them! I'm glad someone actually corrected the issue. NOW, if still available from Fila, bring back the black and shiny silver color...please! :O)
