"I bought two of these, for my daughter and her husband. Light weight, maximum capacity for a carry-on, tough and well made. I've had one for 9 years, traveled lots, and it's in perfect condition. With a carry-on and a tote for underseat, I can travel for 2 1/2 months (roll clothes, select mix-and-match clothes, only 2 pairs of shoes, and take only 1/2 of what you first thought you might need)!"
