Pull the straps of the mask over your head and check the fit of the mask on your face,breath normally to check for any leaks,if you feel slight pressure change when you breath,then you have a good seal,if not ,please kindly adjust the mask wire size. Once in the water,swim on the surface and breathe calmly through your mouth or nose,if you feel light headed remove the mask immediately, keeping your chin slightly up will create the best breathing experience, if you feel any obstruction to your breathing, it may be due to the snorkel being covered in water temporarily , the dry top snorkel design will prevent water from entering through the top of the snorkel , if water leaks into your mask,simply lift your head out of the water and it will drain out of the chin valve,no need remove your mask to clear it of water.
