They sound like those towels they use in some European countries. I suppose they'd be OK if you towelled yourself super fast in a warm room and then threw on a plush robe but because they're so thin they are instantly soaked and cold, so you don't want them in contact with your body for any length of time. I despise them.
just checked out house tweaking... these are now officially on my list. our bathroom is so small and we have limited hanging space too. these look like the perfect solution.
I'm curious too. But I refuse to use a towel more than 1x so maybe it's not for us as I've never had an odor issue from throwing damp/wet towels in the laundry.
