Pretty good solution for only having one backpack.
Very nice pack; lightweight and adaptable to different uses. Stays cool on the back, can hold either a hydration bladder or laptop, and looks really nice (I have the Dark Grey one). It goes from weekday EDC to weekend hiking bag very easily. Only two flaws: 1) it does not stand upright, 2) it lacks a lot of internal organization when you want it (which I solve with a Tom Bihn Freudian Slip).

Great quality bag
Could use a lot more organizational compartments. It's literally just a laptop holder and an empty sack. I love it, I'll probably keep it. Its a very good simple bag. Don't expect to put a lot of items in. Also the side zipper pocket will definitely not fit a phone.

Poor Build Quality
Bag was great for the first 6 months (one month of active school use; one overseas trip) until the inner water sealing (?) began to completely peel off. Extremely disappointed in the build quality; a bag like this shouldn't fall apart in half a year of light use.
