A wider brim would make too heavy; the shoulders would be protected by its own reinforcement

Hi 'Nando,
first of all....Happy New Year to you all.

Interesting point, my concern with the helmet is the 'eye level' (as already stated) but, if your assumption is correct, perhaps the helmet had much more and thicker padding (covering the crown) this would raise the level of the 'brim' in relation to the eyes ...... and increase the protection from falling / downward thrown objects

All the best
