Rubber and PVC are both stiff and can’t form to your face well; they also tend to crack over time. Silicone is more pliable and can conform to the face better, creating a tight seal.This could be caused by hair (especially a mustache), the silicone skirt folding even a tiny bit around the edges or even over-tightening the straps. To get a good seal, there can’t be anything between your skin and the silicone skirt of the mask. Even just a few strands of hair is enough.If you prioritize enhanced visibility, vibrant colors, and an open feeling underwater, clear silicone masks may be the ideal choice. Conversely, if you often dive in bright conditions or prefer reduced glare and fewer distractions, black silicone masks might be the better option.
