What are the signs of a properly fitting mask?

A properly fitting mask is crucial for an enjoyable and safe diving experience. When a mask seals well without excessive pressure, it prevents water from entering and provides a clear view underwater. The ability to easily clear the mask of any water that does enter is also an important characteristic, as it ensures that the diver can maintain visibility and comfort during their dive. This balance of a snug yet comfortable fit allows divers to focus on their underwater activities without constantly worrying about water leaks or pressure points.

Other characteristics, such as a wide field of vision and color, while beneficial, do not directly pertain to how well the mask fits on the diver’s face. Similarly, although the ability to easily adjust the mask or wear it for extended periods are positive attributes, they do not fundamentally determine how effectively the mask seals against the skin. A well-fitting mask is defined primarily by its ability to create a good seal without causing discomfort, which is why this option is the best indicator of a mask that fits properly.
