I've used my Dakine Over/Under bag for over a year and love it. Besides the awesome design that makes it easy for me to spot it on the luggage carousel, it's also extremely versatile. I'll leave it zipped down and smaller for long weekend trips or expand it for longer trips. I've used this suitcase for trips longer than two weeks. The extra pockets on the front allow easy access to an extra pair of shoes or flip flops. There are two zippered mesh pieces on the inside so you can use the two halves to keep dirty and clean stuff separate. It also feels very sturdy and rolls excellently.
