The silicone strap ensures a secure and stable fit on the face during long periods in the water. Our patented, easily adjustable buckle system has made it one of the best models for many years, ideal for recreational and open water swimming. The mask is available with tinted lenses, perfect for outdoor use. If you are looking for the ultimate swim mask on the market, the Cressi Planet is the right mask for you.
