Size Guide

The Neptune III is available in two sizes, Small/Medium and Medium/Large. It is essential to choose a suitable size. You can choose between size S/M (for adults with smaller faces,
women and children over 12 years old) and size M/L (for an adult male, or larger faces).
Measure the distance between the bridge at the top of your nose and the bottom of your chin.
- Choose size S/M if it is BETWEEN (3,9”) 10 cm and (4.5”) 11.5 cm.
- Choose size M/L if it is MORE than (4.5”) 11.5 cm.

There are two different size categories on the chart: Small/Medium and Medium/Large. If the measurements
fall within the both ranges, then the diver should technically be able to wear either full face mask (M/L or
S/M), and in that case should try on a mask to select the best fit. Once the mask is tight on your face, if there is NO SPACE between your chin and
the silicone skirt of the mask, you’ve got the right size.
