No protection for any temporal impact but nice to see another step forward being made by helmet manufacturers. If this makes it to market, I wouldn't be surprised to see the bigger companies follow suit, such as Arai, Shoei, AGV, Shark, X-Lite et al.
The sort of thing that if they’ve got “mates” in the EU policy camp I could see becoming mandatory but I think something like this would be more appropriate, just adapted to fit around a crash helmet?
