you won’t use in the travel (maybe some bag for the trash or for the dirty laundry). there is a cheap and more useful solution.
we all need belts so why not make the best of them for this purpose? it’s a cheap solution because you already have one. and it compress the bag contents and make space for those extra shoes.
just stack up the clothes over belts, possibly two, as shown and pack them in the bags. simple!
