Big or small, the DaKine Over Under Bag has got you covered. This bag has the ability to expand from a smaller 49L bag all the way to a much larger 64L bag. We all know that you gain more stuff than you can hold when you go on a trip, so pack it light and come back heavy with those classic gift shop items for all your friends. Additional features include replaceable urethane wheels, an easy-to-use retractable handle and a split level design for easy access.
