If you want your backpack to make a "statement" about how smart, cool and rich you are, you might not want to buy this - buy a Tumi or another of the high end brands, they will cost you at least 10 times as much. If, on the other hand, you don't care about statements but just want a well designed and made backpack that has some flexibility for your changing life, and you know a great deal when you see it, the Tzowla is for you. The backpack has 2 large compartments, each with pockets, some zipped, inside for small items. The larger of the 2 compartments contains a padded laptop pocket that can accept up to a 17 in laptop, with a velcro'ed retainer strap over the top. This retainer is not really functional for small laptops - there's too much free strap when the Velcro is fastened. There is space in the rest of the larger compartment for a small coat (say, a plastic waterproof) and a bag lunch. This compartment also has 2 stand-out features - 1. wired connectors for buddies/headphones and for charging a device. (You connect a power block inside the bag, then you can charge your device outside the bag, maybe even while you are using it.) It's a little bit gimmicky, but could be useful; and 2. a combination lock - again, could be useful. The smaller of the 2 large compartments is perfect for 1 or 2 books, headphones, kindle/iPad and for travel papers. On the outside of the smaller large compartment is a small easy-access pocket for glasses (reading and sun), passport and phone. There are side pockets for an umbrella (with a retainer strap) and a water bottle, and there is a fixed strap across the front of the bag to secure it on a rollaboard case. The shoulder straps are padded and spread the load well, and there are side straps with clips to compress the volume of the bag to a minimum. The whole bag is made of hard wearing fabric (only black, I think) with a waterproof, spongeable lining, seams are nicely sewn and all of the compartments close with good quality zips and the bag looks good when worn.. Since I have just received my bag, I have not rated it for durability, but it looks like it will last for years. For under $30, look no further.
