The Best of Both Worlds - the revolutionary design of the Fuse X2 makes this the Worlds Lightest Hybrid luggage. The combination of materials allows this luggage to have the strength and support of hard-side luggage with the convenience and functionality of soft-side luggage. Its patent-pending structural design allows the luggage to be completely frameless with all its support coming from the unique skeleton ABS frame. This allows Fuse X2 to be extremely lightweight, weighing just HALF of traditional luggage. The soft-side front panel is made from 400D Taiwanese nylon.
