Cressi Prisma Mask – With FOG-STOP System
The Cressi Prisma combines a compact twin-window mask with internal Fog Stop membranes and external heat-exchange structures. These features help manage the warm, moist air that can reach the lens area, while flexible buckle connectors allow fine strap adjustment. Optional corrective lenses make it a useful model to compare if you want a close-fitting mask with vision-correction support.
Features and benefits
- Fog Stop membranes: Help direct moisture away from the viewing area.
- External heat exchangers: Help manage temperature differences around the lens area.
- Micro-adjustment buckles: Flexible connectors allow movement as you adjust the strap.
- Compact flexible structure: Helps the mask pack neatly.
- Optional corrective lenses: Confirm the exact model and each eye’s power before ordering.
Size and fit
Our catalogue places the Prisma in the small-face group. Try the skirt seal and nose access.
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.
