I purchased the Swiss Gear backpack for two reasons the durability and its waterproof. The cost and liking the item doesn't count as reasons, because I don't think anyone would buy anything who's cost wasn't within reason as well as something they didn't like. I use the back for work, it makes travel easier, the size is just right and it's just want I needed. It doesn't have as many compartments as the first one I purchased for school books, but both Service well for it's intended purpose, tuey were purchased at a reasonable price, they are waterproof and the fabric is built tought.
