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.

Cressi F-Dual + Supernova Dry Mask and Snorkel Set
Enjoy a clear view of the reef with the Cressi F-Dual + Supernova Dry Mask and Snorkel Set. This matched set combines a frameless mask with a dry-top snorkel for beach holidays, reef trips and regular snorkelling. Choose Black/Blue, Black/White or White/Pink, each supplied as one complete set with a carry bag.
A clear view with a comfortable silicone seal
The F-Dual uses one continuous tempered-glass lens, with the silicone skirt bonded directly to the glass. Its frameless construction keeps the profile compact, while the low internal volume means there is less water to clear if the mask floods.
A double-feathered silicone skirt provides two soft sealing edges. Quick-adjust buckles sit on the skirt so the strap can follow your head, and the wide split strap spreads tension across the back of it. Adjust the strap just enough to hold the mask comfortably; overtightening can distort the seal.
How the Supernova Dry snorkel works
A splash guard limits water entry at the surface. When the snorkel goes underwater, its floating dry-top mechanism closes the air opening. This helps keep water out, but a dry snorkel does not let you breathe underwater. Return to the surface and check that the airway is clear before breathing in.
The flexible lower section and silicone mouthpiece help reduce pulling on your jaw. If water enters, the lower collection well and purge valve make it easier to expel with an exhalation. A quick-release keeper attaches the snorkel to the mask strap.
Fit and choosing your colour
Use the Cressi F-Dual dimension chart in the gallery as a reference, then check the seal on your own face. Hold the mask against your face without the strap, keep hair clear of the skirt and inhale gently through your nose. It should hold lightly without uncomfortable pressure. Visit our Hallam dive shop if you would like help checking the fit.
- Black/Blue: black mask skirt and strap with blue accents; matching black/blue snorkel.
- Black/White: black mask skirt and strap with white accents; matching dark snorkel.
- White/Pink: white mask skirt and strap with pink accents; clear/white snorkel.

Care after snorkelling
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 the mask and snorkel in fresh water after each use, including the dry-top mechanism and purge valve. Let them dry in the shade before storage. Keep sand away from the valves and buckles, avoid harsh cleaners and prolonged heat, and follow the supplied Cressi care instructions. Prepare the lens with a suitable mask anti-fog product before use.
