Capacity information is inconsistent: the details list 25.5 litres, while the title and size field give 23–28 litres.

Confirm the selected listing's dimensions and capacity, particularly if relying on an airline's underseat allowance. The listing also describes water resistance and a reinforced waterproof base, but does not confirm a waterproof rating.
