What Makes Streamline Special
Refined, stylish design
Designed with a cool, sunglasses-like look, it's great not only for freediving but also for skin diving, snorkeling and casual fun in the sea or rivers
Even better fit and performance
The 2024 model uses softer silicone for an improved fit. The softer silicone also reduces mask pressure at depth, making diving more comfortable.
Upgraded mask strap
The mask strap is now easier to adjust, and you can pass your hair through the strap, making it especially easy to use if you wear a ponytail
Compact mask volume
Thanks to its low internal volume, you can dive comfortably even beyond -30m
UV-cut lens & anti-fog coating
The lens has a UV-cut and anti-fog coating that protects your eyes from UV rays and reduces lens fogging

FAQs
Yes, they are one-size and unisex, so they can be used by both men and women.
Never scrub the lens. Masks with glass lenses are usually scrubbed with toothpaste before use to remove the oily film, but UMMY's Streamline, Beach and Reef have plastic lenses, so scrubbing will scratch the lens, impair visibility or even cause fogging. Please use them as they are, without scrubbing.
Streamline and Reef already have an anti-fog coating, so no anti-fog is needed. The slippery feel on the inner lens when the mask gets wet is an effect of the coating and is not a defect. (Please do not touch the lens directly. Beach requires anti-fog. In rare cases, using neutral detergent or strong imported anti-fog products may strip the anti-fog coating. Please avoid using detergent or strong anti-fog. If the coating loses its effect with frequent use, please use anti-fog.
Once the lens is scratched, it cannot be repaired or replaced. Plastic lenses scratch very easily, so when handling, strictly avoid the following
- Do not touch the lens directly with your fingers
- Do not wipe the lens with a dry cloth, tissue, etc.
- Avoid using it in very shallow water at the beach, such as the shoreline (pebbles stirred up by waves can hit and scratch the lens)
- Do not place the mask directly on the beach (in contact with sand), and do not put the mask or several pieces of gear unprotected in a bag
- Do not use stick-type anti-fog applied directly to the lens
Freediving masks such as Streamline, Reef and Beach prioritize light weight compared with scuba diving masks, so they are not as strong as scuba masks. Please do not use them for scuba diving.
