Test Facility

The Helmet has been subjected to a series of “stress tests” to verify capacity, resistance and ergonomics, as required by the EN 15333 standard. The result obtained highlighted the high standards achieved in safety and comfort, not to mention an array of ergonomic features including minimized neck fatigue and inhalation effort to the fullest extent, and the provision of an optimized field of vision for increased range and usage practicality.

REAR ANGLE
The helmet’s 30° rear-angled design enables a comfortable donning and removal of the helmet. Donning the helmet is incredibly fast and easy, allowing the Divers to properly close and open the helmet by themselves in a safe and efficient way. When facing upwards the rear-angled design offers a more natural and comfortable method of tilting the head upwards with less stress and fatigue even during prolonged dives.
