Single-lens dive mask GT

This mask is ideal for spearfishing, scuba, snorkeling and fits most adult facial structures. What are the advantages of a well designed Frameless mask and how does it help? By eliminating the plastic mask frame and co-moulding the lens with the skirt, the lens is drawn closer to the eyes which helps increase the divers field of vision. The internal volume of the mask is reduced. This benefits free divers as the amount of lung air required to equalize the mask at depths is reduced. Frameless masks are generally lighter in weight and more streamline. The mask strap fastens to skirt. No more frame squeeze. No more fine sand particles being trapped between the lens and frame which can build up and compromise the integrity of the seal.
