"Borderline" means over by no more than the rounding in published sizes (0.5 cm, about 0.2 in). It may pass at the gate, but we don't promise it.

Notes from our data check

Brand: 'Length: 21.5" (54.5 cm) | Width: 13" (33 cm) | Depth: 9" (21.5 cm) | Volume 35 L | Weight 4.12 lbs'; 'Padded, suspended laptop pocket with soft lining (fits up to 16" laptop)'. CONFLICT on the brand page: 9 in = 22.9 cm, not 21.5 cm; both stored as published. SUPERSEDED: Aer's page says 'There is a newer version of this item: Travel Pack 4 35L' (already in the catalog). It is still sold at $249 (Navy and Olive in stock, Black and Gray sold out). Amazon not checked. Aer's Duffel Pack 3 (named in the brief) was dropped: it is a 21.4 L gym/work bag. Derived values: kg from lb.
