This double-duty roller bag offers 42 liters of space off the bat, with a zippered side expansion panel that adds an extra 15 liters of space. Because the bag is carry-on compatible, Dakine added a large exterior pocket that is the perfect size a 15 inch laptop for quick access at security screenings. The iconic split-level interior design offers individual top and bottom compartments separated by mesh dividers to keep your stuff clean and organized, plus the bag is covered by a limited lifetime warranty so defects and issues are no longer a worry!
