Great design for a backpack!  Tons of pockets.  Great stretch pocket for a water bottle too. But the quality is totally cheap, made-in-china type stuff. Especially the zippers!  These are the cheapest zippers money can buy!  The pack has actually opened on its own twice while I was walking through an airport. Now I know to look for quality zippers on a backpack.  I highly regret buying this backpack.
