The Cressi Big Eyes Maui Snorkelling Set – Red brings together the Big Eyes Evolution mask, Alpha Ultra Dry snorkel and adjustable Maui fins. It suits snorkellers wanting to choose a conventional mask and mouthpiece alongside fins that can be worn barefoot or with light socks.
What is included?
Choose the mask-combo colour and fin size in the bundle options. The mesh bag and other selectable accessories are optional, not standard inclusions. Check your selected extras and quantities before adding the set to your cart.
Mask and snorkel features
- Angled twin tempered-glass lenses: extend the view down towards your equipment and the reef.
- Silicone skirt with varied thickness: combines facial contact areas with supporting sections.
- Pivoting adjustable buckles: help position the strap without needing excessive tension.
- Alpha Ultra Dry snorkel: a float-operated top helps limit water entry when submerged, while the lower purge valve assists clearing.
- Flexible lower section and silicone mouthpiece: allow the snorkel to sit more comfortably at the mouth.
Why choose Maui fins?
The Maui blade combines rigid side sections with a flexible centre that forms a channel during the kick. The adjustable, fabric-covered elastic heel strap has a cleat for fine adjustment and a grab loop to help with fitting.

Maui fin size guide
| Size | EU shoe size | Overall fin length | Overall fin width |
|---|---|---|---|

| M/L | 41–44 | 57 cm | 21 cm |
| L/XL | 44–47 | 59.5 cm | 21.5 cm |
The length and width describe the fins themselves, not your feet. Maui fins suit bare feet or light socks; adjust the fabric-covered EBS heel strap and cleat for a secure fit.

Size charts are a guide only; individual fit varies with foot shape. Check both feet and try the fins with any socks you intend to use. The pocket should hold the foot securely without curled toes, pinching or excessive movement. If you are between sizes, ask our Hallam team for fitting help.

Using your mask and snorkel
A dry snorkel helps control water entry; it does not guarantee a dry mouthpiece or provide air underwater. Practise snorkel clearing and fitting in calm, shallow water. Use a compatible anti-fog treatment as directed and rinse the equipment after each swim.
Care and storage
Rinse the mask, snorkel and fins 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.
