Calpak Luka Large Duffel: 19 x 14.3 x 9.5 in
large-duffel, duffel, no wheels, 2.5 lb empty. Exterior figures are the maker's own.

Calpak states all luggage dimensions in inches on its own product pages. For hardside luggage (Ambeur, Hue) the specifications section explicitly labels the larger figure Exterior, Including wheel, with a separate smaller Interior figure for packing space, so the exterior number already accounts for wheels and handles. For softside duffels and the Terra backpack duffel it publishes a single Dimensions figure since those bags have no wheels. On at least two Ambeur and one Terra product page, an older marketing bullet elsewhere on the same page states a slightly different, usually lower, dimension or weight than the labeled specifications section; the labeled specifications figure was treated as authoritative in this dataset, with the alternate figure noted per bag.
