My husband and I bought these snorkel masks to see the turtles at Maho Bay in St John. Best purchase ever! Fit right on and stayed put! No leaking or having to readjust. My husband has a short beard and it did take him a few tries to get the suction right/leak-free but eventually worked like a charm! Highly recommend!
Great value for money
The seal silicon that goes around the mouth and nose does not come close enough to the face and consequently it leaks air into the upper chamber fogging up the mask. Not sure about CO2 accumulation if exhaling remains around. As I exhale I can feel the wind hit the bottom of my eye lids. The manufacturer needs to add more silicon materiel so as to provide a good seal around the mouth and nose. You need a more robust contact points between the silicon sealer and face. Otherwise, the mask will fog-up especially when you start to exhale with force as you swim. I have noticed that the silicon seal will stretch with time making it impossible to get a good seal. I have tried other brands and found one that works best but again usage is limited before the seal stretches and leakage begins.
A must have for snorkeling!!! Even my kids dive with it and just love it!
