Promate Pro Slender purge mask (MK285) is slim and low profile snorkeling mask with built-in purge and channel at the bottom of the skirt, which direct bubble away from your view. Easy adjust buckles attaching on skirt directly, which makes swivel function more flexible and may fits a wide range of face shapes. Soft and shaped dimples on both sides of nose pocket, which mask equalization easily. High quality silicone to make comfortable and long-lasting fit. Moreover, prescription (Rx) lens (OP270) is available in our product line for this model. Rx tempered lens will be installed in the mask by our trained tecnician.

The lens is tempered glass, which is a type of safety glass processed. Tempering creates balanced internal stresses which cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards. The granular chunks are less likely to cause injury. Comparing with polycarbonate lens, it is usually heavier than the polycarbonate, but the polycarbonate is easier scratched.
