I love this bag. I bought it for carrying around my soccer gear, and it's the perfect size.  The extra zippered pocket on the back is great for carrying my keys/phone/wallet when my shorts don't have pockets.  The mesh side pockets are great for bottles of water or gatorade.
The bag is of very high quality, the ropes are not too small (some bags like this have small rope which cut into my shoulders).
Overall, I think there are no cons/negatives about this bag, I highly recommend it for the price.
