The Easybreath is a special snorkelling mask. It allows you to breathe either through your nose or your mouth while providing a 180° field of vision without having to worry about fogging up, thanks to the air circulation system.
However, to make the most out of it, you should use the right size. If the mask is too small for your face, it’ll be much less comfortable and pleasant to wear, whereas if it’s too big, water might flow inside.
