Desirable mask features include:

Desirable mask features include:

• A. All of the above.
• B. Soft, silicone skirt.
• C. Low internal volume.
• D. Snug, comfortable fit.

Answer: (A)

A good diving mask should seal reliably, be comfortable, and be easy to clear. A soft silicone skirt helps the mask conform to facial contours and form a gentle, effective seal without causing skin irritation. A low internal volume means there’s less air trapped inside the mask, which makes it easier to clear if it leaks and reduces the amount of air you have to equalize as you descend. A snug, comfortable fit keeps the mask in place during movement, reducing leaks and the need for constant adjustment. When you combine these features, you get a mask that seals well, stays comfortable on long dives, and is easy to clear, which is why having all of these attributes together is desirable.
