This is my new favorite bag! It is a great well made bag. The material is strong. It isn't cheap or thin, but isn't really thick to weigh down the bag. The bag is light weight and fits well on my back. It has nice padded straps and even the backing has padding. It has tons of pockets and lots of room in the main compartment. On the inside it has an area separate for a laptop, my 15 fit in there perfect.It also has a side zipper on the side so I can get out my laptop quickly. It also has a pocket on the side of the bag on the inside which has velcro, it is a great place to place smaller items. It also has a back panel for pens and other places to store smaller items like a flash drive, etc. The top is really cool, it not only zippers close but it has tabs to make sure it is extra secure. The flap also goes over the zipper (all zippers have material over them), and this is great to protect the contents from rain. The material seems like it would stand up to some rain and snow and not have a problem. On the outside there is a place for my ipod touch, perfect fit, with a snap, and a little loop where the snap is so you don't damage your MP3 player when you snap it close. It then has a brushed filled pocket on the side with a snap (nicely hidden), where you can put your sunglasses (along with a loop on one strap for one). Then there are side pockets on both sides, on has a clip for keys, and the other is just all open space. Then there is a front pocket for other items that you wish to be able to access quickly. I can't wait to use this bag on my next trip. I know I will be able to put several days worth of cloths in it, easy. This is a great bag to get if you are a man or a woman, traveling or going to work/school. I use mine for school, I put my netbook, cords, mouse, textbook, notebook, folder with papers, along with other everyday things and still have plenty of room for a hoodie and other items with more room to spare. I can't wait to travel with it too.
