If I recall correctly, Skid Lid was sunk by extreme horror that it
gave almost no protection to the top of the head. Every time I've
thunked my helmet it was in the area where Skid Lid concentrated its
protection.

Well, there was that time I climbed a playground slide meant for a
much shorter person and didn't bother to remove my hat first. But
Skid Lid would have sufficed.

I wonder whether there is still a category of hard hat called a "bump
cap"? Wikipedia said yes, but the link led to a page on which the
word "bump" does not appear. DuckDuckGo says that I can buy dozens of
different styles at Grainger.
