Cressi F-Dual Mask Size & Fit Guide
Read the Cressi diagram: Match the lettered rows to the illustration. Dimensions describe the mask, not the size of your face. Where shown, the nose-size scale is Cressi’s comparative reference, not millimetres. Use the chart as a starting point and check the fit on your face.
Check your dive-mask fit
- Keep hair and any hood clear of the sealing edge. Rest the mask on your face without pulling the strap behind your head.
- Inhale gently through your nose to check whether the skirt forms an even seal. Check for gaps at the temples, cheeks and upper lip.
- Check that the frame and nose pocket feel comfortable without pressing on the bridge of your nose. You should be able to reach the nose pocket comfortably.
- Adjust both sides of the strap evenly, using only enough tension to hold the mask in place. Tightening harder will not correct a poor seal shape.
- Recheck the seal with your snorkel or regulator mouthpiece in place and with gentle facial movement. If the shape is uncomfortable or will not seal, try another model.
For help choosing a mask shape, ask our Hallam team during business hours.

Choosing your fit
Keep hair away from the sealing edge and place the mask against your face with light strap tension. Check that the skirt sits evenly around your forehead and cheeks, with comfortable room around the nose. The frame or lens should not press against your face. Visit our Hallam team if you would like help comparing shapes.
Care and storage
Compatible cleaning products
For standard uncoated mask glass, TUSA TEC52 anti-fog treatment is an option when permitted by the mask and treatment instructions. For a separate neoprene strap cover, if you use one, we recommend Cressi Neoclean Wetsuit Wash or Revivex Wetsuit Shampoo to clean compatible neoprene. Wash that component separately according to its care label and the cleaner’s dilution instructions, then rinse thoroughly and dry in the shade. These neoprene cleaners are not a recommendation for the mask lens or a regulator assembly.
Rinse in fresh water after use, including the buckles, then let the mask dry in the shade. Store it in a protective case without crushing the skirt. Follow the supplied instructions for lens preparation and anti-fog treatment, especially for coated lenses. Avoid abrasive cleaners, toothpaste and flame treatment.
