Things I liked:This bag is rugged! It stands up to airline handling, which is as bad or worse than tactical use. You can jam it under the seat in front of you (except in first class, where the seats are lower), and it comes through fresh and unscathed every time. The zippers are just as rugged as the rest of the bag. They move smoothly without snagging, which allows you to pass through airport security fast and easy. Belt, wallet, change, car keys, watch and anything else that's metal drops into the front pocket in seconds. The computer comes out equally fast so you don't hold up the line. The bag has enough storage for a one-night trip. Two nights, if it's casual. The bag comes with holsters and mag carriers that are Velcroed in. They are quick to remove for increased storage. The entire bag is padded, and your computer sits deep inside, so it should never be damaged.
Things I would have changed:I can't think of a thing. I've been on 20 airplane flights with this thing and loving it more every time.
What others should know:Attach the shoulder strap, because this bag will get heavy after a few blocks of walking!
