Build a holiday snorkelling kit around the Cressi Bali full-face mask, Mares X-One adjustable fins and a mesh gear bag. Choose the mask and fin sizes separately so each part of the set suits the wearer.
What is included?
- Cressi Bali full-face snorkel mask with integrated dry snorkel.
- Mares X-One snorkelling fins — one pair at the standard selection.
- Cressi mask, snorkel and fins mesh bag.
Socks and the other listed accessories are optional and are added only when selected. Check your chosen colours, sizes, quantities and extras in the bundle options before adding to cart.
Bali mask features
- Wide polycarbonate window: a broad viewing area for watching fish and reef life.
- Silicone face skirt and adjustable nylon head strap: allow a personal fit when the selected size suits your face.
- Float-operated dry top: closes when submerged to help limit water entering from above. It does not supply air underwater.
- Folding snorkel: makes the mask easier to pack.
- Action-camera mount: accepts a compatible camera; the camera is not included.
Fins for your snorkelling trip
The X-One combines a short two-material blade with a central Channel Thrust section. Its open heel and adjustable strap let you fine-tune the fit within the chosen size range. The compact shape is useful when packing a snorkelling kit.
Choose the Bali mask size
Measure with a ruler from the bottom of your chin to your eyeline. Use the Cressi Bali size guide and check the mask seal against your face.
| Bali mask size | Chin-to-eyeline measurement |
|---|---|
| S/M | Less than 12 cm |
| L/XL | More than 12 cm |
This is a guide only; individual fit varies. If your measurement is exactly 12 cm, or you are between sizes, ask us for fit advice. Face width and shape also affect the seal. Keep hair clear of the skirt and adjust the straps evenly without overtightening.
X-One fin size guide
| Fin size | EU shoe size | UK shoe size |
|---|---|---|
| S/M | 35–38 | 2.5–5 |
| M/L | 39–43 | 5.5–9 |
| L/XL | 44–47 | 9.5–12 |
View the Mares X-One size guide
Choose the X-One fin size independently of any mask size. These are adjustable open-heel snorkelling fins with a barefoot-style pocket. If you want to use thin socks, check the fit before choosing your size; do not assume a dive boot will 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.

Surface snorkelling and care
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.
The full-face mask is for recreational surface snorkelling only. It is not for scuba diving, freediving or breath-hold dives below the surface. The snorkel must remain above the water for you to breathe. Read the supplied instructions, check the mask and snorkel connection, and practise fitting and removing it in calm, shallow water before use.
Stop using the mask if breathing feels uncomfortable. Rinse with fresh water, allow it to dry in the shade and protect the viewing window from scratches. Avoid abrasive cleaners, toothpaste and flame treatments. Follow the mask instructions for cleaning the window and valves.
For a gift, ask for the recipient’s face measurement and usual fin or shoe size before selecting the options. A mask size does not determine the matching fin size.
