Like the title of the product says, it is a daypack. It isn't meant for anything major and it is hardly meant to carry school books but it will do the job if you are just commuting on a bicycle. It has from what I remember 3 pockets on the main body, a small front pocket for your phone/mp3 player, and an expandable pocket for bottled water or an umbrella. There are some loose seams on this that you can just lightly burn closed but aside from that there are few if any complaints that one can make about this product. Considering the quality and price, this sling bag is a good deal.
