Very nice bag.  Will fit under the seat in front of you even on commuter planes.  I hate having to gate check because people try to carry on all their earthly possessions and fill up the overhead bins after only half the plane has boarded.  This bag allows me to keep my important stuff with me even if I loose leg room under the seat in front. Lots of room.  I roll my clothes military style and can get two days worth in this bag along with toiletries and other essentials.
