Make sure there is no sand on the mask or tube,if there has sand,using water to clear the breathing tube or mask,once the mask is clean then it ready for use.
Checking the seal:
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 emove your mask to clear it of water.

?NEWEST SAFETY BREATHING SYSTEN?WSTOO's full face snorkel mask has three completely separate air channels(Intermediate air intake, air outlet on both sides) which can effectively prevent the re-inhalation of exhaled CO2, thus ensuring that you inhale fresh air every time. When you snorkel, you won't feel dizzy or even suffocated by inhaling a mixture of air and CO2, hence maximizing safety.
?AMAZING ANTI-FOG&ANTI-LEAK TECHNOLOGY?The double exhaust passage will double the ventilation speed to prevent the exhaled gas from entering the observation sun visor and causing fogging. We use food grade silicone, safe and non-toxic, good elasticity, and the enlarged silicone skirt is more suitable for your face, effectively preventing leakage. The deeper silicone lining does not put too much pressure on your nose bridge to ensure that you are comfortable to wear.
?Enhanced WSTOO?Our snorkel mask uses a silicone elastic rubber band to connect the snorkel tube. They are foldable, simple to install, take up less space and are easy to store. Two quick release buttons have been added to allow you to quickly get out of the mask and get more self-help time with a button when snorkeling in an emergency.
?180 PANORAMIC VIEW?Our snorkel mask adopts transparent flat lenses that do not distort your view underwater, eliminating any dizziness or discomfort. The 180 panoramic view gives you a clearer view of the ocean world. Additional removable motion camera brackets allow you to easily capture your adventures and share them with your friends and family. It is extremely suitable for beginners, adults, and children. Even for inexperienced swimmers, this snorkel mask full face will make a great fit.
