How Ocean Reef measures
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).
- Nose bridge to chin: Measure the distance between the bridge at the top of your nose and the bottom of your chin.
- Try-on: 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.
