The most important considerations in selecting a mask are fit and comfort.

Your dive will be very unpleasant if your mask leaks, so make sure the skirt fits the contours of your face. To check its fit, hold the mask on your face and have a friend or salesperson check the fit of the skirt. There should be no significant gaps between the skirt and your face.

Next, gently suck in through your nose and tilt your head forward. If the mask remains on your face with minimal suction, the fit is acceptable.

Finally, pull the strap over your head and check for comfort. The skirt should feel soft, and no part of the frame should press against your face.
