The Opto 4 is Samsonite's carry-on hard-shell spinner, built on a polycarbonate shell with a vertical ribbed pattern and a built-in TSA lock. Its standout extras are a hidden Apple AirTag holder and the EazyHOOK strap that lets you link a second bag to the handle. Dual 360-degree spinner wheels and 1.5 inches of expansion make it a practical one-bag-travel pick. Against rivals like the Away Carry-On and Travelpro Maxlite, it leans on the tracking pocket and the 10-year warranty rather than on lighter weight.

Owners of the Opto line generally rate the shell durability and smooth rolling highly, and the AirTag pocket is a commonly cited convenience. Complaints tend to center on scuffs showing on the shell and the hard-sided design leaving little flex.
