Cloth cabin luggage — or cabin suitcases — are usually made of nylon and polyester. They are up to 55 cm long and up to 50 litres in volume. They are suitable for short trips or as an add-on to a normal large suitcase. Most airlines allow you to take them with you on board. Compared to hardshell cabin luggage, they are very lightweight, but since they are soft, they do not provide much protection for the personal belongings inside.
