28" Large Suitcases

Navigator and Meridian measure 75 x 49 x 31 cm (29.5 x 19.3 x 12.2 in) and hold 100 liters. Swiss System measures 78 x 47 x 29 cm and holds 91 liters. Cosmos DLX measures 78 x 41 x 30 cm, holds 120 liters and expands 3 cm in depth, and Americano measures 75 x 47 x 31 cm and holds 121 liters. All of these add up to 155 cm (61 in) or less, under the roughly 158 cm (62 in) limit many airlines set for checked bags.

With 100 liters or more it is easy to go over the usual 23 kg (50 lb) checked bag limit, so the empty weight matters: Swiss System weighs 3 kg, Cosmos DLX 4 kg, and Navigator and Americano 4.3 kg. Put heavy items like shoes at the bottom near the wheels, weigh the case at home, and on an expandable case keep the expansion closed on the way out so there is room for shopping on the way back.

Navigator is made of tough Japanese polypropylene with double spinner wheels coated in silicone. Meridian is full polycarbonate with quiet double TPU wheels and a burst-resistant zipper. Among the softside cases, Americano and Cosmos DLX are made of water-repellent 600D fabric and expand, and Swiss System is a light fabric case with zippered outside pockets.
