I have been diving with a clear silicone mask skirt since the mid-80s when my old black neoprene skirt mask finally gave up the ghost. The neoprene had deteriorated to the point of leaving a black ring on my face. Like most of the diving world, I found the silicone skirt comfortable, well sealing and long-lasting. I never looked back. Now you can’t even find a neoprene mask on the market.
