In 2015 I was asked to make two helmet ideas for ESAB. One which was resulting in a real product - the Sentinel helmet.
The concept "Light head", is more experimental concept and at the time too futuristic for ESAB to develop.
The second helmet "Sentinel" is more traditional but has a more extreme expression which differs it from other welding helmets today. It is now in production.
I have a patent for a new solution of a chin protection from this helmet project.
