I like it!
One thing though, in the article they speak of the ease of removing the helmet in the event of a crash. I can see how much easier it would be to remove the helmet and perhaps save the poor guy's neck. BUT, imagine you're a first responder and you've never seen a helmet like this before. You reach down to cut the helmet's strap so that you can get the helmet off. But wait, where's the strap? How do I get this off?
Troubles brewing.
Here in Oz, our 'First Responder' training was revised to include 'Look for any red tabs/pull tags on either/both sides of the lower lip of the helmet' some years back, maybe even more than 10 years ago now, as more and more helmets included removable cheek pads &/or neck pads to make the helmet safer to take off after an accident. So if your First Responder training has kept up (and I'd guess that it has), they'll already be looking for those red tabs/pull tags, and the training difference between looking for the red tabs to enable removing just the pads and looking for the red tabs in the same place to facilitate removing the entire helmet will likely be pretty minimal at best.
I really like the idea. If the face shield flips up, that would solve the opening problem for me. Looks like carbon fiber, so should be light.
If you look at the left hand side lower edge of the visor in that clip, there's a 'raising point' built into the visor and a thumb depression built into the helmet itself, plus there's visor hinge covers on the side of the helmet, so it's a pretty sure bet that the visor does lift up.
I like to be able the open the front of my modular helmet.
This helmet does not pique my interest. It looks like the face shield does not open and I like the security of a chin strap. Plus I prefer a modular helmet.
See above about the visor opening.

Sure, opening
just the visor is not like lifting the entire chin guard in the way you can on many modular helmets, but then this new style helmet with solid chin guard is also likely to be stronger, safer, less damaging to remove, and there's also adjustable vents built into the chin guard, so you shouldn't feel
too claustrophobic if you
choose to go this way. And I suspect that 'choosing' bit is the big thing about this new style helmet - it's doubtful that anyone will be
forcing you down the path of using this type of helmet; old style chin strap helmets and modular helmets will likely still remain available for those who want them - at least initially, anyway! Altho maybe once the better protection and the far greater safety and less crippling removal aspects of these rear opening helmets become more recognised, that might change and they could become the norm??
Who knows - after all, there was a time when all you could get were those 'borrowed from pilots' padded leather 'helmets'; then the 'inverted soup bowl' helmets; moving on thru half helmets; open face helmets without then with clip-on visors; full face helmets with clip on/non removable visors, then flip up visors; and so on, until we got to where we are today! Innovators are still trying to improve the protection and safety of the most commonly used/readily available helmets, and while some places legislate what you can legally wear when you ride, you can still choose not to go that way if you so desire... that might mean not riding, or paying the fines not wearing a helmet or an appropriately approved helmet, but it's
still your choice!
