I received this Roller Book Bag for a discounted rate in exchange to try and give my honest unbiased opinions. This backpack is waterproof is good quality, and very nice color. This has wheels so you can roll it on ground or carry it on your back. It has 4 zipper pockets where you can put anything you want that fits into it. Side pockets where you can put umbrella, water bottle or small towel. At the back there is a another compartment zipper where there is a bag that you can take out and when it rains you can cover it either on the ground or on your back if you are carrying it. It will not be wet as it will protect the backpack. The wheels are noiseless so it wont be noisy at all when rolling it. I like that it is lifetime warrenty. I like the handle to put it up and it gives you middle or high handle when you switch it up.
