How to choose the size of your spearfishing mask
When choosing your mask, it is best to try it on in store. You will be able to test out the various models and see which one best suits the size and shape of your face.
There is a simple but effective way to test whether a mask is the right size:
1. Position the mask on your face, without using the strap.~
2. Breathe in through your nose: the mask should hold itself in place.~
3. Hold your breath; if the mask does not move then it is the right size. ~
Then put on the strap and adjust it gently without over-tightening: air must be able to get out of the mask.
