The FUGU LUGGAGE suitcase has been designed to be extremely durable; its side panels are made of a special PVC material, “drop-stitch material,” that is used to produce surfboards and flotation devices. This ensures that the suitcase is impact resistant, and strong enough to withstand heavy abuse without incurring damage. We have thrown FUGU LUGGAGE down flights of stairs, dropped it off of a two-story building, placed the prototype under the weight of a car, and subjected it to air pressure tests, in addition to some other serious stress tests, and the walls stayed intact. The inflatable walls have also been designed to be shock absorbent, meaning that not only will the suitcase hold up under extreme conditions, but will also ensure that your items are not damaged, even if the suitcase falls from high up, or is knocked over. We are confident that FUGU LUGGAGE will survive any challenges it may encounter while being transported by airline personnel or at the airport.
