Bluespot mullet “Moolgarda seheli”

Snorkel mask fitting guide. Notice that a good fitting mask will stay on with just a little suction. Now try it with the mask strap on your head. You should get an airtight fit with very light strap pressure. The strap should sit high on the back of your head, not resting on your ears. If it rests on your ears it will get painful. If you have to pull the straps tight to get a fit, or if you have big red marks when it comes off, you have it too tight. A leaky mask is more often a case of straps too tight than too loose. Also, make sure with the mask fully on that you can easily pinch your nose so that you can clear your ears when diving underwater.
