Trying to make my mind up it they're just an unnecessary faff and not helpful, just more 'stuff'
Or if they're actually helping. I am an organised, minimalist person and don't like having loads of stuff unless I love it or it's very useful
I've got a wash bag for toiletries but other than separate bags for different coloured dirty clothes I can't think how they're that useful (dirty whites in one, dirty blacks in another, light dirty colours in another etc, makes washing loads easier when back home)
