adidas is always thinking about the athlete on the go and has done just that with the Fall Midway Backpack. While not created specifically for tennis, this backpack can be carried to the courts. On the smaller side, it has one main compartment with a laptop sleeve (you could throw a racquet in there but the zippers do not lock in place if they are not touching and all the way zipped). Two accessory pockets on the front will hold your small items and there are two bottle pockets on either side. 

• Dimensions: L12.25"  x W8.25"  x H18.5" 
• One main compartment with a lined laptop pocket (we don't recommend this for holding a racquet)
• Two front accessory pockets for accessories and small items
• Dual elastic, mesh side pockets for cans of balls or water bottles
• Color: Black / Blue / Red
