Yes, it is a unisex free size and can be used by both men and women.

Never rub the mask. Generally, masks with glass lenses are rubbed with toothpaste to remove the oil film before use, but UMMY's Streamline, Beach, and Reef have plastic lenses, so rubbing the lenses can scratch them and reduce visibility, or even cause the lenses to become cloudy. Please use the mask as is without rubbing.

Streamline and Leaf are anti-fog treated, so anti-fog is not necessary. When the mask gets wet, the inner lens of the mask becomes slippery due to the effect of the coating, which is not abnormal. (Do not touch the lens directly. Anti-fog is required at the beach. In rare cases, using neutral detergent or strong anti-fog made overseas may cause the anti-fog coating to peel off. Please refrain from using detergent or strong anti-fog. If the effectiveness of the anti-fog coating weakens with frequency of use of the mask, please use anti-fog.

Once a lens is scratched, it cannot be repaired or replaced. Plastic lenses are very susceptible to scratches, so please do the following when handling them:

• Do not touch the lens directly with your fingers.
• Do not wipe the lens with a dry cloth or tissue.
• Avoid using the camera in very shallow waters such as near the beach (small pebbles are likely to fly around and scratch the lens).
• Do not place your mask directly on the beach (where it touches the sand) and do not put your mask or multiple pieces of equipment in a bag or other container.
• Do not use stick-type anti-fog products

Freediving masks such as Streamline, Reef, Beach, etc. are designed to be lightweight compared to scuba diving masks, so they are not as strong as scuba diving masks. Therefore, we recommend that you do not use them while scuba diving.
