Mike, I did notice that the insides of the gloves were soaking wet with perspiration when I removed them - better that my hands are wet with that than black oil, of course.
When I read your post, my engineering mind went into design mode and thought, "drain hole", but, of course, immediately rejected that - if the sweat can find a way out, the oil can find a way in. Surely, physicians who wear these all the time have found a way to handle the sweat, wouldn't you think?
