The Aqualung Plazma Scuba Diving Mask is a great choice for divers who want a top-quality mask that will provide them with superior visibility underwater. This mask has a clear, tempered glass lens that offers an unobstructed view of the underwater world. The mask also has a comfortable silicone skirt that conforms to your face and creates a watertight seal. Additionally, the Plazma mask has a unique "double-sealed" frame that prevents water from leaking into the mask and causing discomfort.
