The Cressi Quantum Dive Mask & Itaca Dry Snorkel Sets brings together a twin-lens mask with condensation-control features and a dry-top snorkel. Check the mask fit and snorkel mouthpiece independently so both suit the wearer.
What is included?
- Cressi Quantum mask.
- Cressi Itaca Ultra Dry snorkel.
Fins are sold separately. Choose the colour combination offered on this listing; a colour name does not change the need to check the mask’s seal.
Mask features
- Inclined tempered-glass lenses extend the downward viewing area.
- Internal membranes help direct exhaled moisture away from the lenses.
- External heat-exchange structures assist temperature balancing.
- Flexible micrometric buckles and a bi-silicone strap allow fitting adjustment.
Snorkel features
- Closing Aquastop top helps limit water entry when submerged.
- Flexible lower section lets the mouthpiece sit naturally and move aside when released.
- Angled silicone mouthpiece and lower purge valve support positioning and water clearing.
- Adjustable mask attachment allows you to set the snorkel height.

Cressi Quantum size chart
This chart applies to the Cressi Quantum mask in this set.
| Manufacturer skirt-fit guide | Between regular and wide (Cressi chart marker) |

| Skirt chart measurements | A: 12 cm; B: 11.5 cm (Cressi chart references) |

| Manufacturer nose-size scale | 5 on Cressi’s 1–5 reference scale |
Cressi’s measurements are reference points on the diagram. They describe the skirt and nose area, rather than overall frame dimensions or a guaranteed facial fit. Check the seal and nose-pocket comfort before choosing.

The Fog Stop features are designed to help reduce condensation; they do not guarantee fog-free use or replace correct fitting, lens preparation and care.
Fit and choosing your set
Please check the Cressi size guide chart where shown and use it as a reference only. Mask measurements describe the equipment and do not guarantee a fit for a particular face. Keep hair clear of the skirt, use light strap tension and check brow, cheek and nose-pocket comfort. If buying as a gift, allow time for the wearer to try the fit before their trip.
Adjust the snorkel keeper so the mouthpiece rests naturally without pulling on the lips. Practise breathing and clearing in calm, shallow water. A snorkel only supplies air while its opening is above water; a closing dry top does not provide air while submerged.
Care and storage
Rinse the mask and snorkel in fresh water after each swim, removing sand from the buckles, straps and snorkel top. Allow everything to dry in the shade before storage. Use a suitable anti-fog treatment as directed and avoid abrasive cleaners, toothpaste or flame treatments. Check the skirt, mouthpiece, valves and straps before each use.
