Bag design is great with the zips hidden against your back to stop naughty fingers. It's just big enough for my macbook pro 15 (without velcro'ing it in). I can usually get enough gear in for an overnight trip: laptop + cables + rolled clothes + toiletries, which makes it easier through checkin. It's comfortable even when fully loaded. The only issue is some airport security guys still make you take the laptop out, and some others love the design and point it out (even at the same airports which is annoying!). Highly recommended.
So I like the bag have got some use out of it. But the only down side is that the zipper shows when you pack the bag up, so it kind of defeats the purpose of it. Other than that good bag for the money.
