How to choose a leak-free snorkelling or diving mask for the Maldives

The essential fit test is simple: place the mask on your face without the strap, inhale gently through your nose and let go. A suitable mask should stay in place by suction; if it falls off or leaks air, try a different shape.

For diving or snorkelling, look for lenses marked “Tempered,” meaning tempered glass. Plastic lenses are not recommended for diving, and the mask skirt should be soft silicone with no strong smell.

Do not choose a mask by brand name alone: Tusa is one option to try, but face fit matters most. It is also best to avoid masks with valves, as they add an extra component that can fail.
