The new High Seal material and the design principles followed in the skirt construction ensure a very large contact point between the face and the mask. The Big Eyes Evolution mask fits the face with great ease without leaving marks on the skin, even after prolonged use. To achieve this, the mask's skirt has a different construction with internal reinforcements in areas that experience higher pressure. Inclined drop-shaped lenses are positioned as close as possible to the eyes, resulting in a 25% greater visibility compared to the already outstanding visibility of the Matrix mask.
