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