The Cressi SF1 Mask is the newest of Cressi’s frameless masks. The SF1 is based upon the bestselling F1 Mask, the S standing for “square”, the F for “frameless”.
The SF1 is a frameless mask, with the silicone skirt attached directly to the tempered glass. This helps with the vision in the mask, as there isn’t a frame in your peripheral vision. There are many benefits of using a frameless mask. You can fold up the mask flatter to fit into BCD pockets as spare masks. Frameless masks can provide more vision, along with a more streamlined look.
Developed with a silicone skirt, the SF1 has tilt-able, durable buckles that allow easy adjustment without movement of the silicone on the face.
This mask is a standard fit and fits most average sized faces.
