Since there’s no such thing as too much packing space, the ZDX 29” Large Expandable Spinner gives you more, with 2.5” of zippered expansion depth and Briggs & Riley's patented Outsider® handle for a flat, roomier interior. Lots of other thoughtful details include a Smartlink strap for connecting two bags, a roomy, gusseted outer pocket for a jacket and an easy-to-grab bottom handle, all designed to keep you and your stuff merrily rolling along.
