A built-in expansion mechanism makes it possible to enlarge the hard-shell Spectra 2.0 Medium Expandable suitcase by up to 11 cm while its dimensions can be further adjusted using external compression straps. This is how the suitcase can offer up to 47 per cent more packing capacity. The polycarbonate trolley is engineered to be lightweight without sacrificing durability. Its surface is solid and features reinforced edges. The suitcase can easily be packed from the top and its multiple compartments ensure the contents are kept neat and tidy.
