All lies in the correct installation of the mask

You have a tending to take long natural breaths but if water splashes into the snorkel you can get caught mid breath and your immediate reaction is to panic for lack of air

I did speak with many snorklers who had other full mask snorkelsfrom other manufactures and all liked that the hicool has a longer snorkel causing less frequency of water leaking into the snorkel

I really enjoy it but make sure its your size because if its too big or small for your face itll leak water

It never fogged up because of the airflow through the eye portion i could breathe normally through my nose or mouth and the air tube stopped all water from intruding whenever i dived

It is hard to pack this item and i was too afraid to remove the snorkel once clipped into place as it is really snug and i was afraid i would break it attempting to do so

Also my asian nose and bridge are small so there was not a good seal around my mouth and nose but the mask still worked fine anyways

After initially having difficulty with the product and writing an unhappy review this company immediately reached out to me to rectify the situation
