I've stashed this great bag in overhead bins and checked it.  It rolls nicely, and after a few miles of cobblestone sidewalks, it is still my favorite traveling bag.  The front zip pocket has a smaller secure pocket for incidentals.  I keep a bag bungee in the front pocket to secure a smaller tote on top.  The material seems durable, and the bag is well-designed overall.  The handles on the top and sides are easy to spot and grasp.  Mine is blue, which makes it easy to find, though I always add some bright blue painter's tape to each side so my bag is distinctive enough to keep it from being confused with anyone else's.
