I also find them a great expedient clothing hanger for hanging wrung out hand-washed clothing at my accommodations. It works better if you have or share a private room with a window.
I carry several, long "trash-can rubber bands," and a couple of largish plastic "S" hooks, to loop over the ends of a curtain rod, or other protuberance, to suspend my hiking poles horizontally. These bands and hooks weigh "nothing." Really, just a few grams, and they have a myriad of uses. They go into a separate zip-lock baggie as my laundry line kit.
In colder months, or when it is raining, I hang this horizontal arrangement over a radiator, if one is available. This gets the early morning blast of heat.
Then again, I also carry 2 - 3 folding plastic clothing hangers. They fold up very small and flat - smaller than the palm of your hand, and only weigh a few grams each. Once unfolded, they can hold a wet, wrung out fleece garment. Locate them on Amazon.
Hope this helps.
