WHAT’S THE CORRECT MASK SIZE?
The Neptune Space G.divers is available in two sizes, Small/Medium and Medium/Large.
In order to determine whether a diver should wear a S/M or M/L mask, OCEAN REEF has
designed a Mask Measuring Kit. The sizing and measuring system were designed in
accordance with the official measuring procedure used in the Los Alamos Scientific
Laboratory Charts at the SBCCOM Mask Fit Facility-Aberdeen Proving Ground (Maryland,
USA).
Before purchasing a mask, the customer may use the calliper to take two simple face
measurements. Using the Full Face Mask Size Recommendation Chart, he or she can
evaluate the size category into which the measurements fall. There are three different
size categories on the chart: Small/Medium, Both, & Medium/Large. If the
measurements fall within the both category, 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. Please note that the chart boundaries fade. The fading areas represent less
common face measurements. It is very likely that a mask will still fit comfortably even if
measurements are located in these fading areas.
