Fugu Luggage avoids the need to shell out for an extra suitcase to fit all that extra gear by expanding from a maximum carry-on size to check-in size suitcase in under a minute.

Named after the Fugu, or pufferfish, the Fugu Luggage expands from a compact carry-on size to a full-sized suitcase courtesy of its accordion-like side walls. To comply with the maximum carry-on size limitation of airlines, the case measures 21.5 in (55 cm) wide, 13.5 in (35 cm) deep and 9 in (23 cm) high with a volume of 40 L in carry-on mode, extending to 27 in (68 cm) high with a volume of 120 L when fully extended. The Fugu tips the scales at 8.8 lb (4 kg), which the creators say is comparable to other average-sized luggage.

Converting from compact to full-size modes involves inflating the suitcase walls, which are made from drop stitch, a rugged PVC material used in inflatable boats. This can be accomplished either with an electric pump built into the case, an external pump, or with lung power by breathing into an external tube. The Fugu's built in pump can also be used to deflate vacuum bags to minimize the volume of clothing when packing.

Since luggage isn't just intended to carry your belongings, but also protect them while still being lightweight enough to drag around, the Fugu team claims the drop stitch walls can take a beating, as can the top and bottom of the case, which are made of ABS plastic. The Fugu team says the case is waterproof and impact resistant and has successfully passed an altitude drop test.
