Cressi A1 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 A1 Dive Mask
The Cressi A1 combines an inclined single lens with a silicone skirt and a double-rim upper seal. The teardrop viewing shape extends the downward view, while frame-mounted buckles on flexible tabs help you adjust the strap without pulling directly on the skirt. This is the existing A1 listing, with standard and UV420 options as shown; the separately listed A1 Anti-Fog is a different configuration.
Features and benefits
- Inclined single lens: Provides a broad window with an extended downward shape.
- Double-rim upper seal: Adds a second edge around the forehead.
- Flexible buckle tabs: Retain movement at the frame connection.
- Soft silicone strap: Provides flexible head contact.
- Version-specific finish: Only the option explicitly marked UV420 carries that listed treatment.
Size and fit
Cressi’s chart places the skirt between regular and wide. Check the nose pocket and upper sealing edge on your face.
Keep hair clear of the sealing edge and hold the mask gently against your face. Check even contact at the cheeks and forehead, plus comfortable access to your nose. Use light strap tension; overtightening can distort the skirt rather than correct the wrong shape. If you wear a hood, check the fit with it in place.

Care and storage
Rinse the mask in fresh water after every outing, flushing salt and grit from the skirt, strap and buckles. Use mild liquid soap only where the mask manufacturer allows it, then rinse thoroughly. Dry in the shade and store with the lens protected and the skirt relaxed. Check the strap and sealing edge before use. Avoid abrasives, toothpaste and flame treatments.
Follow the supplied instructions for the selected lens finish. Use only cleaners and defoggers expressly approved for that coating or prescription lens. Gear Aid Sea Drops is not recommended for prescription lenses or anti-reflective coatings. A mirrored, UV or anti-reflective finish does not itself replace anti-fog preparation. For clear, uncoated options, TUSA TEC52 anti-fog treatment is an option when the mask and treatment instructions permit it.
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.
