Being stuck for a cabin bag that I could use on a flybe flight (they don't give as much carry on allowance as other airlines) I came across this. It's a well made little bag; however, please note the little. Even though I drew out the sizes (yes I was that anal) to make sure it would fit, when it arrived it was a lot smaller than I was expecting. For an overnighter though it works fine. In fact it would make a great everyday bag for a school person, or a work bag as there are several different compartments within it that all fasten making it nice and secure to keep all you could need in.
I'd have preferred it's big brother (note to makers to make a big brother) but it does what you need it to do.
