Aqualung Sphera X Freediving Mask
The Aqualung Sphera X is a low-volume freediving mask with curved Plexisol plastic lenses. Its close-fitting shape and flexible silicone skirt suit divers who want a compact mask with an open view, with clear and mirrored finishes offered through the selector.

- Curved Plexisol lenses provide a wide viewing shape without the weight of glass.
- Advanced Fit Technology shapes the silicone sealing surface to help the skirt settle against your face.
- Micro-adjustment buckles and a shaped silicone strap help you fine-tune the position.
- A zippered EVA protective case helps protect the lenses during transport.

Choosing the fit
Hold the mask gently against your face with the strap out of the way. Keep hair clear of the silicone skirt and check the seal, nose clearance and pressure around your brow and cheeks. Use only light strap tension: tightening the strap cannot correct an unsuitable skirt shape. If you are buying a gift, ask our Hallam team about fitting before choosing by appearance alone.
Protecting the plastic lenses
Plexisol needs different care from untreated tempered glass. Do not use toothpaste, abrasive lens cleaners or flame treatments. Follow Aqualung’s instructions for the lens finish selected, avoid rubbing the inside surfaces and rinse away salt and sand before storage.
Care and storage
Compatible cleaning products
For a coated, prescription or anti-fog-film lens, use only the cleaner or defogger approved by that lens manufacturer. Gear Aid Sea Drops is not recommended for prescription lenses or anti-reflective coatings. 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, dry in the shade and protect the lens in a case. Follow the supplied cleaning instructions and use only a suitable anti-fog treatment. Avoid toothpaste, abrasive cleaners and flame treatments, especially on plastic or coated lenses. Check the skirt and buckles before use.
