Frequently asked questions
How does compression work?
Store your clothes in the compartment, close it, then suck out the air with the included mini electric pump or with your vacuum cleaner. The clothes flatten out: you take more without exceeding the dimensions of the free baggage.
Can you take the pump when traveling?
Yes, it is small and fits in the bag: practical for recompressing your clothes before returning.
Is it accepted free of charge at Ryanair?
Yes: at 40 x 20 x 25 cm, it fits in the free Ryanair baggage of 40 x 30 x 20 cm, under the seat.
Does the bag stay the same size once filled?
Yes, if it is not stuffed to the point of swelling: the compression helps to keep the bag flat and in shape.
