I bought this bag on a whim because the reviews on here were good and the price was awesome. It does not disappoint. It has an amazing amount of room and I feel that it protects my HP Zbook really well. I would not recommend dropping the bag with your laptop in it to test it but I did hit the bag pretty hard to see how it held up and I did not even feel the impact on the laptop. So it seems like it will be able to protect a computer. The thing that impressed me the most is the build quality of the bag and the amount of room it offers. You could easily use this as a weekend bag if need be. I have put in 2 or 3 changes of clothes, a bluetooth speaker, a collection of cables, my zbook and some paper work and still had more room for other stuff. It really is amazing the amount of things this thing can hold but yet it is not bulky. You can tell thought went into designing this bag. It feels and looks like a bag that is easily at the $100 price point. Very recommended and you really can't go wrong for $30 or so!!!!! Thank you KROSER!!!!! You will be my first choice for my next bag.
