Why do I need the correct size snorkel mask?

Before we show you how to find the right size let's explore why it's important to have the correct fitting size full face mask. Reef Mask's are designed to create air pockets around the mouth, nose and eyes. This allows swimmers to be able to breathe comfortably and naturally as they explore the ocean. All Reef Mask's are made to be comfortable around the face, giving you a full 180-degree view.


When it’s loose

Just like traditional snorkel masks you want them to fit snuggly on your face and tight around your head. If your full-face mask is loose then there is a strong chance it can slip off. When the mask is loose water easily seeps into the head region, not only is this frustrating it can also be dangerous for swimmers.


When it’s  tight

You never want to have your full face snorkel mask too tight, this can hinder the overall experience in a negative way. When the strap is too tight you will notice issues such as migraines, headaches & neck pain. Overuse of a tight snorkel mask can do long-term damage so it's important to ensure your Mask fits correctly.
