Tradition
Innovation
Performance
Since its beginnings in the early 1900s, DRASS Galeazzi continues its legacy of innovation in the commercial diving sector. Extensive field experience coupled with decades of innovative technological advances brought DRASS Galeazzi Research & Development to embark on its latest cutting-edge project in 2017: the design and development of the D-ONE Drass Diving Helmet.
D-ONE represents the highest echelon of product which DRASS proudly offers to the market.
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.
