love this bag! I will never check luggage again, thanks to this bag. I rarely ever write reviews, but i am so happy with packpro, I wanted to share. I fit 8 lightweight dresses in the garment back, and 6 ball caps and a few other things in the duffle bag and it all fit nicely underneath the seat in front of me on Southwest. I did scrunch it a bit to fit it all the way under, but it did fit! I was able to put my other bag in the overhead compartment. No more long lines waiting for luggage! I have told everyone I know, who travels a lot about this bag.
