Yes, it's the French Adrian helmet, introduced in 1915.

testing has shown the Adrian helmet, because of it's crest, does a better job at protecting the head against overhead blasts than the modern US Army helmet.

A team of biomedical engineers compared the U.S. Advanced Combat Helmet, which is being phased out, to three designs from WWI — the French Adrian, the British Brodie and the German Stahlhelm helmets — in extensive testing designed to simulate the effects of overhead explosions.

Traumatic brain injuries can be caused by the pressure resulting from detonations from artillery shells, aerial bombs or other ordnance. The injuries often have long-term effects that are difficult to detect immediately.

The study, published earlier this month, said that while ballistic protection afforded by modern helmets is much better than in WWI, the ACH did not provide better protection against overhead blasts than any of its WWI predecessors.

Specifically, the French 1915 Adrian helmet produced a lower peak pressure at the crown of the head compared to the ACH, it said.

The Adrian was characterized by a crest along its dome. This provides an additional layer of protection that absorbs the shock to the wearer’s head, in contrast to helmets that don’t have that feature.

“The Adrian helmet resulted in lower crown pressures than all other cases,” the study found. “The ACH, Stahlhelm, and Brodie helmet were not found to be significantly different from each other,” the study found.

The Army’s ACH has been in use since the mid-2000s but is being steadily replaced by the Enhanced Combat Helmet.

Meanwhile, the Army’s new Integrated Head Protection System helmet has been fielded by units in Afghanistan and elsewhere with promises of better protection against blunt impact.
