Mask features
- Anti-reflective lens treatment: Helps reduce reflections on the lens surfaces for a clearer view.
- UV420 lens treatment: Adds UV and short-wavelength light filtering to the optical glass.
- TRI-MIX frame: Provides a reinforced structure around the lenses.
- Freedom Technology with Fit II: Uses a shaped silicone skirt to balance flexible contact with support.
- Optional corrective lenses: Compatible MC2001SA negative lenses let you tailor the mask to your vision needs; they are sold separately.
Twin CrystalView lenses have anti-reflective and UV420 treatment. The reinforced TRI-MIX frame and Freedom Fit II silicone skirt support adjustment.
Snorkel features
- Closing dry top: A float-operated gasket closes the upper opening when submerged, helping keep water out of the tube. It opens again above the surface to admit air.
- Angled high-flow purge: Collected water sits near the covered, large-diameter lower valve, giving it a short exit path when you clear the snorkel.
- Shaped silicone mouthpiece: The contoured bite and flexible silicone neck let the mouthpiece settle comfortably without the upper tube pulling directly against your jaw.
- Comfort Swivel attachment: The detachable, two-part mask adapter rotates so you can set the tube angle and remove the snorkel without repeatedly threading the mask strap.
Fin features
- PuRiMaX polyurethane blade: a responsive blade compound for controlled propulsion.
- 20° angled blade: positions the blade relative to the foot pocket for the kick cycle.
- Vortex Generator ridges: shape water flow behind the blade vent.
- Adjustable bungee heel strap: stretches over the boot heel for fitting and removal.
- Modular HyFlex construction: detachable blade and foot-pocket components; check compatibility before purchasing replacement parts.

Mask fit and choosing a gift
Face width, shape and nose-pocket comfort matter more than a general age or gender label. Keep hair clear of the skirt and check for an even seal without pressure around the brow or cheeks. Use light strap tension. For a gift, confirm the recipient’s fitting needs before selecting lens powers or fin sizes; our Hallam team can help compare options.
Mask fit and specifications
| Face-fit profile | Medium–large (TUSA 2026 skirt-fit guide) |
|---|---|
| Buckle adjustment | Angle Strap Adjuster with Side Hold |
The fit classification follows TUSA’s 2026 skirt-fit guide. Check the seal, brow clearance and nose comfort on your own face; the fit label is a starting point.
HyFlex Switch size guide
| Fin size | Foot length guide | EU shoe size guide |
|---|---|---|
| XS | 22–24 cm | 34–38 |
| S | 24–26 cm | 38–40 |
| M | 26–28 cm | 40–44 |
| L/XL | 28–32 cm | 44–50 |
This guide is for the SF0104 configuration with a combined L/XL size offered on this listing. TUSA also publishes charts for newer configurations with separate L and XL sizes; do not substitute those rows for the combined L/XL option. All sizes are fit guides, not a guarantee of fit.
These are open-heel fins for use with dive boots. Boot thickness, sole shape and foot width affect the fit, so try the fin with the actual boots you will wear. The heel strap should hold the boot securely without forcing your toes against the end of the pocket. Boots are sold separately with the standalone fins.
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.

Using and caring for your equipment
A snorkel supplies air only while its opening is above the water. A dry top helps limit incoming water but does not allow underwater breathing. Practise fitting, breathing and clearing in calm, shallow conditions before a longer 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.
