The Avant Collection holdall bag maximizes carry-on capacity. It does this with Interlink™, our proprietary magnetic-mechanical latching technology. When connected to the Avant carry-on luggage, it provides an additional 16 liters of storage space. That’s a storage space increase of 36%. It is constructed of our proprietary hybrid shell so that it protects like hardshell luggage, but remains lightweight and flexible. Its form is tall and narrow so that it’s especially ergonomic and maneuverable in tight spaces, like airplane aisles. Though designed to work in connection with the Avant Collection carry-on luggage, it can be used individually for day trips. It also features a grip and a shoulder strap made from Italian leather so it can be carried apart from the luggage.
