Bell Helmet produced a hard-shell helmet sometime in the mid-80s that was not as dorky looking as their original white helmet. I don't know the name of that particular helmet but it mimicked the thicker hairnet helmets in terms of look, while complying with the codes of the day. The shell was thick plastic, not the paper-thin stuff of today, and it was high-density EPS for shock absorption.
I don't know of anything today except for perhaps Bell's Citi helmet, in black.
