Baseball style cap, with a hard insert, installed. The inserts come with a hard plastic shell and a soft cushioned lining on the top of the shell. The hard shell helps absorb accidental top impacts. That turns your regular cap into a soft safety bump cap that is still comfortable to wear. These caps are supportive, stylish, and functional. Unlike some similar products on the market, these soft caps don’t contain metal parts, so you never have to worry about replacements.
