Just read a couple of reviews on the viscose towels. The reports say that they don't hold up, and will tear if rubbed against a day old beard, or caught on a fingernail. Also, you can't wash them out as hand washing will separate the threads, and machine washing will utterly destroy them. Has this beent he case in your use of them?
