Catlin, If you are going to be in Europe for a long time, like a few months to study, then perhaps bring it with you, but only if you're not into using the flutter, acapella, and a good ol' beating. The new vest IS small and really helpful at home, but traveling with it is a PAIN. I was going to take mine to ALabama for a month the last time i went to visit my father. I had my doc write a letter stating what it was for. When I got to check-in, I was told that it was too big to carry-on (it had a duffle bag, and it was really too heavy for me to carry), so it would have to be checked. I asked if I could check it at the gate like a stroller, because we all know how damaged luggage can get at the airport. So I lugged it to security, where they took everything out of the bag. Needless to say they had never seen anything like this before, I explained what it was used for and showed them my note. I think they made a note of my name and what flight I was on (which I didn't particularly like). Anyway, it was so heavy to carry in the airport and such a hassle, I ended up shipping it home before I returned. I don't know if you've ever been to Europe before, but traveling there is exausting. You can take the vest, but I'm gonna suggest not to. Sometimes I take it on road trips, but I usually just travel with my accpella or flutter, and do autogenic drainage and that works fine.Debbie22 yr old w/ CF
