Bottom Line: The Osprey Transit Bag makes your commute a bit more bearable.
I enjoy this bag a lot. I've used it the rain and it keeps my books and computer dry. I also like the back zipper because if I just want my computer I don't need to deal with annoying front zipper. It sticks. That's my only complaint. It's kind of annoying in the middle of class trying to get something out of your bag and you have a tough time getting it unzipped
I saw some reviews saying that the strap was annoying when carrying a lot of weight. Well, this is a shoulder bag and they aren't made to carry a ton of weight and be comfortable at the same time. That's what day packs are for. Any loaded book bag or shoulder bag is going to feel a little uncomfortable, so pack light or deal with it.
Good bag. Used it everyday for two years. The only hangup is that the waterproofed zipper was pretty tight at the beginning, making getting in and out a little difficult. it eventually loosened up, but then the rubber/plastic coating started to deteriorate and break off. Zipper worked, but it looked ugly.
While the bag itself can hold plenty in terms of volume and mass, the strap and shoulder pad are thin so you may feel the weight across your body.
These reservations aside, I like this bag at the price I paid.
