"Holds everything I own and feels comfortable, but might not be convenient for everyone."
This bag is very big and because of the expandability and straps I feel pretty comfortable and secure no matter how lightly or heavily I'm packed. The biggest problem is that it's not so easy to get to the things that are near the bottom of the bag. The side zipper sometimes helps but for me is rarely used because it's kind of awkward.It's mostly waterproof, the heavy rain I put it through was no problem. It has amazing build quality and extremely durable fabric.
