The regular-to-large fitting guide is a starting point only. Check the seal, cheek clearance and nose-pocket comfort before selecting the mask.
Choosing your fit
Keep hair away from the sealing edge and place the mask against your face with light strap tension. Check that the skirt sits evenly around your forehead and cheeks, with comfortable room around the nose. The frame or lens should not press against your face. Visit our Hallam team if you would like help comparing shapes.
Care and storage
Rinse in fresh water after use, including the buckles, then let the mask dry in the shade. Store it in a protective case without crushing the skirt. Follow the supplied instructions for lens preparation and anti-fog treatment, especially for coated lenses. Avoid abrasive cleaners, toothpaste and flame treatment.
