This is a sturdy bag that is spacious without being bulky or oversized. I carry miscellaneous items back and forth to work in it.

The interior water bottle pocket is the perfect size for a reusable water bottle (mine is the 24 oz. size).

The bag seems able to handle lot of weight; I even carried a gallon of milk in it from the store to my car.

The zippered mesh pocket inside is about 3.5 x 8 inches, which is the right size for a small set of keys, pens, business cards, etc. But since it is the only zippered pocket, I wish it were larger.

The bag's major flaw (which is why I give it 4 stars) is the absence of a zipper across the top, so I wouldn't recommend it for travel, but it's fine for trips in the car back and forth to work. It seems that High Sierra could charge a few extra bucks and make this bag with a zipper. Otherwise, a great tote that you can't go wrong with!
