Mask features
The Cressi A1 combines a single inclined lens with a soft silicone skirt and a lens treatment intended to help manage fogging. The downward-extending window is useful when checking your equipment or looking below you.
- Inclined single-lens layout extends the downward viewing area.
- Treated tempered-glass lens helps manage condensation when used and cared for as directed.
- Double-edged upper skirt provides a flexible sealing area.
- Frame-mounted buckles sit on flexible tabs and allow one-hand strap adjustment.
- Soft nose pocket provides access for equalisation.
Snorkel features
- Float-operated dry valve: The upper mechanism closes when submerged to help limit water entering the tube.
- Smooth inner flex section: The corrugated silicone neck bends on the outside while its smooth inner surface helps water move through the tube.
- Angled silicone mouthpiece: The replaceable bite lets the mouthpiece meet your mouth at a comfortable angle.
- Water well and elliptical purge: Water gathers in the lower collection area, where a large elliptical valve provides an exit during clearing.
- Quick-release keeper: Adjust the snorkel height beside your mask and detach it without repeatedly unthreading the mask strap.

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.

An anti-fog treatment does not guarantee fog-free use in every condition. Follow the supplied lens-care instructions and avoid abrasive cleaners, toothpaste or flame treatment.
Face width, shape and nose-pocket comfort determine mask fit. A small, medium, large or youth label is a starting guide only. Keep hair clear of the skirt and use light strap tension; do not overtighten a mask to compensate for a poor fit.
Snorkel fit and use
Adjust the attachment and check the bite before your first swim. The mouthpiece should stay in place without strong clenching. Select the colour shown in your chosen option.
Use the snorkel for breathing at the surface with its opening above the water. Clear any water before taking your next breath; a snorkel does not supply air while submerged.
Buying for someone else
If this is a gift, ask about the wearer’s current mask fit and allow time to check the seal and mouthpiece comfort before the first trip. Mask size and mouthpiece comfort need separate checks. Our Hallam team can help compare suitable shapes.
Care and storage
Rinse in fresh water after use, including the buckles, then let the mask dry in the shade. Store it in a protective case without crushing the skirt. Follow the supplied instructions for lens preparation and anti-fog treatment, especially for coated lenses. Avoid abrasive cleaners, toothpaste and flame treatment.
Flush the snorkel, mouthpiece and any valves with fresh water after use. Remove trapped sand and let the equipment dry in the shade before storage.
