The Dakine DLX Roller 80L travel bag features 4940 cubic inches of space measuring approximately 29 x 16 x 15 inches. At that size, it's not Dakine's largest travel bag but certainly not a carry on. It's a good medium sized bag. The split level design with a mid zipper opening allows for easy access and interior organization pockets (one is fleece lined) makes organization a snap. Replaceable urethane wheels, a cinch style laundry bag, and bottle opener by the handle complete the package.
