An expandable zip changes the exact dimensions it claims to fit
This size band is the one most travelers check for a week-long trip, and the feature that most changes what a case actually holds is an expandable zip gusset — typically adding 15-20% more volume at the cost of the case no longer measuring the dimensions printed on the listing once expanded. We compare stated capacity with and without expansion, empty weight (which eats directly into a checked-bag allowance before anything is packed), and how the wheel housings are reinforced, since this is the point that fails first on a case handled roughly by baggage systems.
66 cm (26 in) · 57.5 L · 4 wheels
A lighter, simpler medium case in the same Bon Air family as the cabin size — a lower price than Samsonite's own S'Cure at a very similar footprint.
Best for: A budget-conscious medium case for travelers who do not check luggage often enough to justify the pricier S'Cure.
≈ $275
67 cm (26.4 in) · 60-66 L · 4 wheels
The medium Chios keeps the lightweight positioning of the cabin size, at 60-66 liters and the lowest confirmed price in this hub.
Best for: Occasional travelers prioritizing low weight and price over long-term ruggedness.
69 cm (27.2 in) · 79 L · 4 wheels
The medium-size step up from Samsonite's S'Cure cabin case — the same flexible polypropylene shell and four-wheel spinner set, sized for a week away.
Best for: Travelers who already trust the S'Cure cabin case and want the matching checked size.

Medium · expandable · 4 wheels
Delsey's medium case adds an expansion zip that the cabin size does without, giving genuine flexibility for a return trip with extra packed items.
The volume decides how long you are covered without washing on site. It is the most versatile format in the aisle.
Four swivel wheels let you push a full medium case with no shoulder effort. The gain is felt as soon as the weight rises.
Fifty-millimeter wheels catch on every joint; seventy-millimeter ones roll over them. The stated wheel diameter is what changes the strain of the walk.
A medium format is enough for most travelers. The limiting factor is the airline's weight limit, not the volume.
A well-filled medium case easily exceeds the hold limit. Weighing at home avoids a surcharge at the desk.
It can be forced and sometimes gives way when overloaded. Frame closures are more secure, heavier and dearer.
Heavy items on the wheel side, laid flat at the bottom. A case loaded at the top topples the moment you let go.
Sets sold together are designed for it. Two cases from different makers rarely nest.
It can be washed, which counts after a trip. Many linings are sewn in and do not come out.
Little on the spot: the case pulls crookedly. That is why the availability of spare wheels matters at purchase.
On smooth ground it pushes alongside you effortlessly. On an uneven pavement or a slope, two tilted wheels hold the line better.
The limiting factor on a medium case is the weight limit, not the volume: weigh it before leaving. Load heavy on the wheel side and flat, and know that a zip gives way under overload more easily than a clip frame.
A characteristic joins the table when four bags in five give it. Below that, the column would say nothing useful.
