Used it as a carry on for the items that I did not want to check.

No I didn't pay too much attention to the dimensions. I read all the reviews about how big it was, perfect for carry on etc. I assumed it was comparable in size to my llbean medium adventure duffle (carry on size), but these bags were much smaller. I purchased four of these for my children to use for summer vacation and they BARELY served that need. My 8yr old was able to pack comfortably, but 10, 12, and 14 yrs olds were stuffed. Had I realized I would have chosen a different bag. So- this bag is fine. Not especially well made, but it is not expensive so that is to be expected. It is sized more as a weekend bag- If you need something more than that I suggest getting something else.

Cheap zippers. The nylon is thin but sturdy. Side pockets are small. End pockets are decent sized. Great for a gym bag. A little small for overnight.
