Lens finish depends on the selected option. Anti-fog treatment does not replace correct fit or lens care, and it does not guarantee fog-free use.
Choosing your mask fit
Choose by face shape rather than age or gender alone. Keep hair clear of the sealing edge, hold the mask gently against your face and check brow, cheek and nose comfort. Adjust the strap with light tension; tightening it harder will not correct gaps from an unsuitable skirt shape. If you are buying as a gift, check the recipient’s existing fit or ask our Hallam team for help comparing models.
Care and storage
Rinse in fresh water after use, flushing sand from buckles before adjusting them. Let the mask dry in the shade and store it without crushing the skirt. Use a suitable anti-fog treatment as directed. Avoid abrasive cleaners, toothpaste and flame treatments, particularly on coated lenses or fitted anti-fog films. Follow the supplied lens-care instructions and check the skirt, strap and buckles before use.
