Many of Cressi's newer generation dive masks are equipped with IDF (Integrated Dual Frame) frame technology, and the Calibro is no exception. The mask is designed to create an extremely hydrodynamic and compact unit with the front and frame, featuring lenses that sit very close to the face. The field of vision is phenomenally wide, enhanced by the angle of the frame. Clearing the mask is very easy due to its very small internal volume. The buckles are directly integrated into the silicone body, making them solid yet flexible. Thanks to the matte finish, all components of the mask visually match, enhancing the underwater experience by eliminating reflections in the water that could disturb marine life. The Cressi "Anti-Fog" system is also utilized in the Calibro. It is the perfect mask for freediving, but of course, it is also well-suited for scuba diving and snorkeling.
