This is another excellent Dakine bag. Very sturdy, good quality - I've owned many Dakine packs, and they have all held up amazingly well over many years. We have taken at least ten trips of various lengths with this and it's holding up great. My husband and I are able to share it on shorter trips because of the dual-zone zipper compartments. Fits in the overhead (when not expanded). Outside zipper compartments are very convenient and hold a lot. It rolls well, but it does wobble going down curbs sometimes, particularly when the bag is expanded - but, honestly, it's fine even rushing through cities. It stays upright on its own, which is very important because it's terrible to have your bag falling over in the airport lines. It also matches my awesome Dakine backpack:) I LOVE DAKINE BAGS!!!
