Before I get obvious replies to this question, I did a search the only reply is over 2 years old.

Now to my question. Does anyone have any recommendations for backpacks? I have a few requirements:

- Waterproof
- Light attachment points
- U-Lock storage

I have looked at some the the Mission Workshop bags, some like the Vandal. My concerns are I ride 18 miles one way to college, in my bag I carry a 13" MacBook Pro, a iPad, iPhone, toolkit, change of clothing (usually just shirt and shorts), spiral bound paper, and pens, pencils. I currently have a messenger bag and the reason of looking for a new bag is because my messenger bag is a little to big.

Normally I would look at panniers, however being on a college campus I don't feel that is the most secure choice.

Does anyone have any suggestions of bags or experiences?
