Streamline's commitment

Stylish and refined design

The cool design gives the impression of wearing sunglasses, so it is recommended not only for free diving, but also for skin diving, snorkeling, and casual beach and river activities.

More pursuit of fit and functionality

The 2024 model has a softer silicone that improves the fit. The softer silicone reduces the burden of mask pressure at depth, making diving easier.

Mask straps have evolved

The mask straps are now easier to adjust and you can now pass your hair through the straps, making it especially convenient for those who wear their hair in a ponytail.

Compact mask volume

The mask volume is small, so you can dive to depths of -30m or more with less strain.

UV protection lens & anti-fog processing

The mask lenses are UV-resistant and anti-fog, protecting your eyes from UV rays and reducing lens fogging.

Characteristics of each color

Demon t Buck

A basic color that matches any style and is popular among both men and women, making it difficult to pass UV rays to your skin.

Demon White

It goes well with brightly colored wetsuits and swimsuits, the most popular color among women.

Demon t t t t t t t t t t t t t t t

A cool, unique color that goes well with both swimsuits and wetsuits

Demon t Cee

Even the frame and silicone skirt are clear, so the field of vision is wide and the whole thing is clear, making it difficult to burn the mask.

I'm looking forward to seeing you

It stands out underwater, protects your eyes from the strong sunlight, and maintains stable vision on sunny days.

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.

Usage notes
  • Due to the curved lenses, some people may experience slight distortion in their vision or feel sickness when wearing the mask.
  • If you rub plastic lenses with an abrasive such as toothpaste, the lenses will get scratched. Please use them as is without rubbing them.
  • When using for the first time, do not dive to deep depths (-30m or more) immediately, but gradually increase the depth while testing the fit.
  • If your physical condition is poor, your mask may not fit well, the straps may be too tight, or you may experience mask squeeze (the mask being pressed against your face due to water pressure) or difficulty equalizing your ears, even at shallow depths, depending on your skill level. If mask squeeze does not go away even after blowing the mask (breathing out of your nose to return the mask to its original position), or if you are unable to equalize your ears and continue diving, you may suffer from internal eye bleeding, nosebleeds, headaches, or eardrum inflammation or rupture. If you feel any abnormality, immediately stop diving and, depending on the situation, seek medical advice.
  • After use, wash with fresh water, avoid direct sunlight, and hang to dry immediately.
  • Since the lenses are made of resin, they are easily scratched if they come into contact with other equipment. To ensure long-term use, please store them in a case or bag after use.
  • Please be sure to follow the instructions when handling masks.HereRead the blog
