Built to withstand the rigors of technical diving, the Teknika?s two-piece shock resistant frame is assembled with AISI 304 stainless steel bolts and screws for superior strength. The twin-lens design provides an excellent field of view and the dark skirt eliminates distracting side-light, a feature many technical divers appreciate when spending long hours in the water. Wide headpiece on silicone strap conforms to the user?s head to ensure a comfortable, secure fit. High-grade silicone material allows the facial skirt to flex and naturally mold around facial contours for a leak-free seal. Shatterproof, tempered glass lenses suitable for diving and snorkeling meet ANSI standards. Color options: Black skirt ?
