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.

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.
Optional extras
The following items are additional selections and are included only if you choose them:
- OceanPro Lycra Fin Socks For Snorkelling & Diving.
- Enth Degree F3 Socks.
- TUSA Snorkelling Bag (SB-31).
Anti-fog film is shaped for particular lenses. Check the film’s listed mask compatibility and the supplied fitting instructions before applying it, especially with coated or corrective lenses.
Use, care and storage
Compatible cleaning products
For a coated, prescription or anti-fog-film lens, use only the cleaner or defogger approved by that lens manufacturer. Gear Aid Sea Drops is not recommended for prescription lenses or anti-reflective coatings. 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.
