More pronounced inverted tear-drop shaped lenses, raked inward to sit even closer to the eyes, and built overall more compact make the Matrix an ideal choice for divers and free divers looking for the biggest view in the smallest package. The Matrix has a wide field of view, with a double feathered edge 100% hypoallergenic soft silicone skirt. It's extraordinary inverted tear drop lens visibility, together with its extreme comfort and efficient adjusting low-profile buckle system for the wide split style silicone strap makes this model a great choice for all diving activities. The Dry Snorkel has an anti-splash top end with a special valve that seals the tube as you dive, almost totally preventing the entrance of water when the snorkel is submerged. The lower end has a corrugated section that has a smooth internal bore which prevents trapping water inside the snorkel tube allowing excess water to quickly drain to the collection reservoir below. The corrugated section also quickly drops away from the diver's mouth when switching from the snorkel to the Scuba regulator.
