They're really great. My brother and I used them for a ten day trip to France in October and we could have easily carried on if we wanted to, even after buying stuff while there. I really recommend them. The small one you can get for about $18-25 and the larger ones for about $25-30. Like I said, they also have pouches for the underwear and socks etc that keep those all nice and compact. Glad you like them too, ExperimentalAB...I think they should be part of the "industry norm" as well!!
