Product Information
The Ocean Reef UNO Full Face Snorkeling Mask is a full face snorkeling mask that lets you breathe naturally through your nose while on the surface, built with a 180° panoramic view and a dry-top snorkel that helps keep water out. Made in Italy, it is designed as an entry-level full face mask for snorkelers who want a wide field of vision without a traditional mouthpiece.
Who it is for
This mask suits snorkelers who want to breathe through the nose instead of biting a mouthpiece, and who want a clear, wide underwater view. It is available in two sizes, S/M and L/XL, and it is built to work with the rest of the Ocean Reef full face snorkeling mask accessory line. The UNO is not intended for free diving, though swimming submerged at shallow depth is possible.
Key details
- Field of view: 180° panoramic design for an expansive underwater view.
- Breathing system: dry-top snorkel with a purge valve, engineered to limit water entry while breathing through the nose.
- Anti-fog technology: a patented, independently tested air-circulation system helps prevent fogging.
- Strap: silicone strap for a secure, durable hold.
- Breathing resistance and CO2 concentration: Breathing resistance and CO2 figures of 8.53/7.26 mbar and 0.8% are Ocean Reef full face mask line averages under EN1972 and EN136 methodologies.
- Country of manufacture: Italy.
Compatibility and sizing
The UNO is offered in S/M (Small/Medium) and L/XL (Large/X-Large). It is compatible with the Ocean Reef full face snorkeling mask accessory line, including the Snorkie Talkie communication unit, the Optical Lens Kit, Duo fins, and the Camera Support accessory.
