Materials are all cheap nylon and feels really light and flimsy.  the zipper pulls are all tiny and hard to grasp.  I have found that it is difficult to pick a good backpack online.  Better off going to a store and checking the item out first hand.  This is the second backpack I bought that was very disappointing.  With daily use it will probably last a year or so.  As a knock around backpack {if sold for about 22.00}it would be worth it, otherwise this is not the quality pack your looking for.
