The Seac Symbol is an Italian-made two-glass diving mask featuring a 3D buckle directly on the mask body. The edge is slightly curved to enlarge the sealing surface, reducing discomfort and marks on the face for optimal comfort even during prolonged use. The 3D tilt buckle with two buttons makes it easy to adjust the silicone strap of the mask. Angled 3 mm thick tempered glasses provide excellent visibility and high durability. Prescription lenses for nearsightedness and farsightedness are available separately.
