The SeaFire is the favored mask for freedivers due to it low volume
The amazing low volume of this mask is achieved using “single-shot” technology
Rather than use a traditional “snap-together” frame, the Freediver mask uses an internal frame to keep the volume low and keep drag to a minimum.
Since the lenses are located so close to the eyes, the peripheral vision is outstanding
Swivel buckles are integrated into the mask frame
