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. It features inclined and inverted tear-drop lenses for improving downward visibility, a Cressi patented design (US 6272693). Perfect for checking the BCD and the instruments while scuba diving. The field of view is particularly wide, laterally and in the lower zone. The lenses are made of tempered glass. Extremely low internal volume on par with the best free diving masks. Ideal for easy-equalization. The hypoallergenic soft silicone skirt shaped provides a wide sealing surface for a leak-free fit. The nose pocket is soft and easy to reach. Micrometric adjustable buckles allow precise head strap adjustments.
