This bag pack is big and quality products, not so much of the design though. The side pockets are with the zip which is good for not loosing items place in there but not good to put water bottle in there. but if you are just looking for a big backpack, doesn't mind the design and doesn't need to place a water bottle on the side pocket, this may be 5 stars item for you although it doesn't fit my need and I give 3 stars only.
