A large main compartment with panel access makes packing cubes and clothes easy to organize.
Multiple grab handles help during tight plane aisles and quick overhead lifts. The harness stows for cleaner checked transit, though you will likely keep it carry on.
Front pockets manage small items, while compression straps keep the load from ballooning.
