55 x 35 x 20cm48L expanded2.5kg empty2-year warranty, direct only
A 21-inch soft-shell cabin case at 55 x 35 x 20cm, wheels and handles included. The 35cm width is the useful number: it sits 5cm inside Ryanair's priority gauge, so a full case still goes through without a debate at the gate. 48 litres with the 4cm expander open, 2.5kg empty.
