The soft portion of the dive mask that makes a seal against your face is called the skirt.
For a scuba diving mask to be comfortable and have a good fit, it’s vital that the skirt has a great mould and is constructed from comfortable, high quality material.
In the case of the Cressi Focus; it’s skirt is constructed from hyperallogenic silicone – which is both insanely durable and also extra soft for added comfort.
Admittedly; most scuba masks today are made from soft silicone; it’s kind of the norm because of well it works.
Where dive mask skirts do vary more, is in the specific mould that they have; the proportions and contours, the angles and connection points.
For this, the Cressi Focus stands out because of the fact that it’s skirt is widely cited by many divers as fitting any kind of face type whatsoever – whereas other masks can often be described as fitting well – if you have a big face or a small face etc.
In the Cressi Focus, it seems to fit all face types like a dream.
It’s also a nice bonus that you can choose for the frame to be clear or black.
