The Aqualung Teknika Mask is designed for technical diving, with a two-piece frame that is shock-resistant and assembled with strong AISI 304 stainless steel bolts and screws. This twin-lens design offers a wide field of view, while the dark skirt helps to eliminate distracting side-light for long hours spent in the water. The techno-polymer frame can withstand rough treatment on the dive deck and in the water, with added strength from the corrosion-resistant stainless steel bolts and screws. Plus, the mask is compact and easy to carry as a back-up option in a BC pocket, with cardanic joint buckles for a customized, pinch-free fit and convenient strap adjustments, even while wearing gloves. The high-grade silicone material and wide headpiece ensure a comfortable and secure fit, while the shatterproof, tempered glass lenses meet ANSI standards for diving and snorkeling. Choose from a black skirt option for a sleek look.
