RichardCStudy Finds Century-Old Combat Helmet Is A Superior Shield Against Brain Trauma

It was only when those helmets were exposed to overhead blast waves that the 1915-era Adrian helmet outperformed the others. The Duke researchers point to the raised metal crest running from the front to the back of the Adrian helmet — a design feature also found on helmets used in those times by French firefighters — as a likely explanation for its superior protection from overhead blasts.
"The geometry of the helmet can make a big difference," says Op 't Eynde. "I'm not sure a crest or something like it would work with a modern design, but just being aware of how the geometry might affect the way that the head and the brain might experience a shock wave is definitely something that I think should be kept in mind in helmet design."
If the crest actually works to redirect the pressure waves, it shouldn't add that much weight to the current design.
