Black silicone skirts eliminate peripheral refracted light, allowing your pupils to open further to accept only the light source emanating from your immediate field of vision. Your eyes are then able to register a greater clarity of depth, detail and colour resulting in what you see coming alive with vibrancy and colour.... It's magic! It's black magic. The reflective lens gives this low volume, high quality mask a distinctive finish. Unique reflective lens won't spook the fish with eye movement. Snorkel comes with a dry tip and purge. A top of the range set for the experienced diver.
