Freedom Technology The mask has a dimpled skirt around the cheeks and forehead to offer a superior seal to flat skirts in these areas. This increases the skirts softness and suppleness in these critical areas reduces the chances of leakage. The skirt has various thicknesses of silicone which in areas around the mouth which distort whilst holding a snorkel or regulator again offer a superior seal. As water pressure increases all masks push harder onto your face until you equalise the pressure.

The technology with the mask means the edges of the skirt are made from low friction silicone with offers superior softness and fit. If you struggle to find a dive or snorkel mask to fit, your search may be over.
