When selecting a face mask, the most important thing to consider is

• A. Color
• B. Strap length
• C. Proper seal and fit
• D. Lens type

Answer: (C)

The essential idea is that a mask must form a reliable seal against your face. The edge that touches your skin, the skirt, is what keeps water out and creates a stable air space for your eyes to look through. If the seal isn’t right or the mask doesn’t fit your facial contours, water will leak in every time you move, breathe, or look around. That leakage obscures vision, can cause distraction, and can even create safety issues underwater. So choosing a mask that matches your face and can be fitted to form a snug seal is the most important factor. To check it, test the seal on your face and gently inhale through your nose to create a slight suction; the mask should stay in place without water leaking in. If it leaks, try a different size or shape, or adjust the skirt fit. Color, strap length, or lens type may affect comfort or vision, but they don’t determine whether the mask will keep water out.
