I want to buy a drybag for washing clothes while backpacking (travelling, not hiking) and also keeping dirty/wet clothes until it is time to wash them.
I have available near me 5L, 10L and 20L dry bags, they are almost the same price. For washing clothes I think the 10L would work, but since they are close in price and weight, is it better to pick up a larger size? Can I keep rolling it down to compress it more?
Also, those dry bags are made from polyester with PVC "sealing" (loose translation here).
PS: Couldn't find better keywords for this question.
