A folding Boston bag that satisfies both "function" and "mood". It has a large capacity that can hold luggage for 2 nights and 3 days. When folded, it becomes so compact that you can't believe it's a large-capacity bag. Even in a carry case or travel bag It can be carried without bulk. It can also be expanded by opening the zipper at the bottom. I bought too many souvenirs to get in! At such times It is also very convenient for storing clothes for two people. The outer material is water-repellent. You can use it with confidence even in sudden rain. If you pass the handle through the through hole, you can also carry it on. Of course, not only for travel, It is also recommended as a sub-bag for everyday use.
