Seac Symbol is a Made in Italy two-glass diving mask with a 3D buckle directly on the mask body. The rim is slightly curved to increase the sealing surface, reducing discomfort and marks on the face for optimal comfort even during prolonged use. Two-button 3D tilt buckle facilitates adjustment of the mask's silicone strap. Angled 3 mm tempered lenses provide excellent vision and high durability. Optical lenses for nearsightedness and farsightedness are available separately. Want to use the Seac Symbol with your action cam and record your underwater adventures live? Check out Seac Symbol Pro.
