Cressi - Nano
The new Cressi Nano mask is the lowest volume mask in the world. It's great for freediving and spearfishing, and offers an extremely hydrodynamic and compact shape. The internal volume is minimal allowing a small equalization effort. Angled tempered glass lenses are close to the eyes offering an excellent field of vision. The swiveling buckles feature micrometric regulation. The strap is robust and stretchy.
