Julien Bergignat and Patrice Mouille have designed a helmet that is super lightweight and collapsible. Pretty interesting design and concept, as it allows for the user to fold the helmet up and slip into a backpack when not riding.
The only problem is that it just doesn’t look like it can protect the head from any sort of impact at all. And that is the sole purpose of the helmet; to protect the head.
It would probably be a wise decision to hold on to your Snell/ASTM approved helmets, and save this one for your Knight’s Tale: The Musical rehearsal.
