/lightweight
There is nothing like carbon fiber (CFRP). A mere 370g (0.82 lb) is the new benchmark for a surgical helmet. You might not even notice that there is something on your head.
/quiet
Imagine having a walk in the woods, a slight breeze blows through the leaves. That's the level of noise you will experience inside the ViVi® helmet.
/perfect balance
Nothing pulls on your neck, the virtual center of mass is inside your head.
/vision
A large field of vision is everything. The ViVi® helmet provides for a 190 degree distraction free view.
