It’s quite the trend to have suitcases with an expandable hood to accommodate more clothes and stuff. However very few have stopped to consider vacuum packing clothes, to make more space. The Pumpack is one such suitcase design where it includes a pump that helps to compress clothes to make more packing room. For those who are going to complain about creases, I suggest you carry a travel iron. I for one think we need to develop this design thoroughly!
