The compact twin-lens Matrix takes the basic design concepts of the Big Eyes Evolution and pushes them to a new level of performance. More pronounced inverted tear-drop shaped lenses, raked inward to sit even closer to the eyes, and a more compact build overall make the Matrix an ideal choice for divers and free divers looking for the biggest view in the smallest package. The Raked lenses provide excellent field-of-view. The Inverted tear-drop lenses improve downward visibility for managing BC-mounted gear. The Extremely low internal volume on par with the best free diving masks. The Silicone skirt is shaped to provide a wide sealing surface for a leak-free fit. The Micrometric adjustable buckles allow precise headband adjustments and the over moulded frame is easy to grip Streamlined and compact, the Gamma is easy to pack for warm water vacations and an excellent choice for divers and snorkelers who appreciate the confidence and cleanliness of using their own equipment.

The Adjustable clip is made for securing the snorkel to any mask. The High-quality silicone mouthpiece is comfortable and durable and the Angled mouthpiece reduces jaw fatigue.
