Big and Roomy! Rolls easy. So far, this bag is a dream. I used a backpack for 2 years traveling every week. My backpack was too heavy for slinging over 1 shoulder and not very graceful or professional trying to get out of both shoulder straps in the clients office. I've tried other roller bags, but they didn't have the room and storage options that this bag has. It is big. It easily holds my 17" brick of a laptop with extended battery. Plenty of room for cables, cords, micro projector, a couple of tablets and everything that goes along with constant travel. So far it appears to be durable. I worry about the zippers, but only because they are so quiet and smooth.

It does fit in the overhead of a CRJ-900. It was a tight fit and I will underpack it a bit more the next time, but it did fit.
