The Seal 2.0 features a curved lens to deliver 180-degree panoramic vision, as well as having a silicon skirt that alternates matt and shiny surfaces to cleverly increase the seal. This makes water penetration virtually impossible whilst producing a very comfortable soft-touch feel without feeling any pain on your face. The silicone head strap, which features a 100 per cent silicone micrometric buckle system that is simple to adjust while the mask is one your face. The split strap sits comfortably around the head without irritation. Both the buckle system and nose bridge have been carefully streamlined to deliver enhanced hydrodynamics over the original Seal mask.
