This is just what I was looking for to replace my 15yo or so Targus bag.This bag doesn't quite hold as much as my old Targus bag. But I did recently travel with it and it had enough capacity for what I was bringing. My Targus bag wouldn't fit under the airline seat, but this one did. There are straps on the side that let you cinch something to the bag. I used the to hold my sweater and winter coat as I walked through the airport. It was nice to be able to not wear them but know they were held securely by the bag.I have a 17" laptop and it fit in the bag. A bit tighter than I'd like, height-wiser, but I had no issue closing the bag. It fit.When I got the bag delivered and I picked up the box, the box was HEAVY! The bag is made of heavy duty canvas and is made to last. While it's fairly heavy, It was still OK to travel with.One thing I don't like about this bag is that the laptop compartment doesn't open flat. Not a big deal because my airport is lame and makes us take out all electronics bigger than a cell phone anyway. ? The other thing I don't like is that the bottom back compartment only has one zipper, so you have to zip it all the way around. I wish there were two opposing zippers on that compartment.The zippers appear to be of good quality.I like that the bag can convert to an attache style bag with tuck away straps and handle.Also, the color is beautiful.All in all, a good, high quality, heavy duty bag that ought to last me another 15 years.
