This Cressi package pairs the Big Eyes Evolution mask and Alpha Ultra Dry snorkel with Agua Pro full-foot fins. It suits shoppers who want the downward view of the Big Eyes lens shape and prefer a foot pocket without a heel strap.
What is included?
The standard configuration includes:
Mask and snorkel features
- Cressi Big Eyes Evolution: Angled inverted-teardrop lenses extend the downward view. A dual-density silicone skirt, flexible buckle mounts and micrometric adjustment help you settle the fit.
- Lens layout: Twin tempered-glass lenses.
- Cressi Alpha Ultra Dry: A float-operated top helps limit water entry when submerged. The flexible lower section, silicone mouthpiece, quick-release keeper and purge valve assist positioning and clearing.
Included fins: Cressi Agua Pro
A responsive blade and self-adjusting foot pocket suit snorkellers who prefer a full-foot fin.

Mask fit and buying as a gift
Use the mask’s fit profile as a starting guide only. Face width, cheek shape and nose clearance matter more than age or gender. Keep hair clear of the skirt and adjust the strap with light tension. Check that the mouthpiece sits naturally without strong clenching. For a gift, check the recipient’s current fit and foot size where possible, or ask our Hallam team for help before choosing.

Mask and skirt dimensions in a manufacturer chart describe the product; they are not a guaranteed range of face widths. Check the actual seal, frame clearance and nose comfort.

Use the Agua Pro chart for this model, rather than borrowing dimensions from the Agua or Agua Short.
Open the Cressi Agua Pro manufacturer size chart
These fins are intended for bare feet or suitably fitted thin socks. Check both feet and select from the sizes offered on this pack. A charted size may not be available in every colour. The fin should feel secure without pinching, curled toes or excessive movement; do not choose loose fins just for growing room.
To measure your feet, place paper against a wall, stand with your heel gently against the wall and mark your longest toe. Measure from the wall to the mark in centimetres. Repeat for the other foot and use the longer measurement. Where a model has no foot-length chart, contact us with that measurement and your usual shoe size rather than using another fin model’s chart.
Use, care and storage
Compatible cleaning products
For standard uncoated mask glass, TUSA TEC52 anti-fog treatment is an option when permitted by the mask and treatment instructions. 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.
A snorkel supplies air only while its opening is above the water. A dry top helps limit water entry but does not provide air underwater or guarantee a dry mouthpiece. Practise fitting and clearing in calm, shallow water before heading out.
Rinse the equipment in fresh water after use, including buckles, straps, snorkel valves and fin pockets. Dry in the shade before storage. Use mask-care products as directed and avoid abrasive cleaners, toothpaste or flame treatments. Inspect the mouthpiece, skirt and straps before the next swim.
