About these measurements: Soft bag. Weight published as 2 lb 1 oz / 0.975 kg. Can be worn as a backpack.
May be bigger than listed when full. The brand lists 40 L of capacity, but a bag of this listed size can only hold about 39 L. Packed full, it will be larger than the numbers above, so treat its fit badges as a best case.
Laptop size is the sleeve size the brand lists. Laptops with the same screen size differ in width and thickness, so compare your laptop's own measurements if it is a snug one.

A badge means the published size fits the airline's published limit. It is never a guarantee to board: an overstuffed bag, weight limits and fare rules can still apply. "No published limit" means the airline lists no size for that bag type, so we do not judge it. Airlines change their rules. Always confirm size limits with your airline before you fly.
