Cressi Rocks Junior Mask, Snorkel and Fins Set - Large / X-Large Cressi Rocks Adjustable Fins Size Chart
Fit note: Packaging: S/M [3–5] and L/XL [6–10] match the approximate age ranges in Cressi’s chart.
Fit note: Choose by measured foot length first. Ages are approximate; they are not shoe sizes.
Fit note: Cressi specifies barefoot use for Rocks. Adjust the heel strap for a comfortable, secure fit.
How to measure your foot
- Place paper on a hard floor against a wall. Stand barefoot with your heel gently touching the wall.
- Keep your weight on the foot and mark the end of your longest toe, holding the pencil upright.
- Measure from the wall to the mark in centimetres. Measure both feet and use the longer measurement.
Foot length in centimetres is the best starting point, followed by EU sizing, then US sizing.

The Cressi Rocks Junior Snorkelling Set combines a junior mask, splash-guard snorkel and adjustable Rocks fins in a mesh carry bag. It is an easy way to gather the essentials for a child’s snorkelling holiday while choosing the fin size separately from face fit.
What is included?
- Junior mask with tempered-glass lenses.
- Junior snorkel with splash guard.
- One pair of adjustable open-heel Rocks fins.
- Mesh carry bag.
Features and benefits
- Tempered-glass lenses and adjustable mask strap: clear viewing with adjustment around the head.
- Semi-dry splash guard: helps deflect splashed water at the surface. This is not a dry-top shut-off snorkel; it can fill when submerged.
- Vented composite fins: compact blades with a soft foot pocket for junior snorkelling.
- Adjustable heel straps: release buckles and thumb loops help with fitting and removal.
Size and fit guide
Approximate junior age guide: 7–12 years. This is a guide only; individual fit varies. The mask seal and mouthpiece must suit the child, and the fins must be selected by foot fit. Please check the Cressi size guide chart as well as the rough age guide.
Use the size options on this listing and check the actual fin fit. Different Rocks set generations carry different size labels, so contact us with your child’s foot length in centimetres if you are unsure. These Rocks fins are designed for barefoot use. Do not choose a larger size simply to match an age bracket.
| Rocks fin size | Overall fin length | Overall fin width |
|---|---|---|
| S/M | 34.8 cm | 17 cm |
| L/XL | 37.9 cm | 17.7 cm |
These measurements describe the fins themselves, not the child’s foot length.
Children of the same age can have very different face shapes and foot sizes. Check the mask seal, mouthpiece comfort and fin fit separately. Keep hair clear of the mask skirt and adjust the strap without overtightening. The child should be able to hold the mouthpiece gently with their lips closed around it.
Practise fitting, surface breathing and snorkel clearing in calm, shallow water with active adult supervision. A snorkel is not a swimming aid and only supplies air when its opening is above the surface.

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.
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.
