As you said, Capix makes an affordable "wake helmet."
COC stands for Camp of Champs. Probably some kid running around with a di-cut on his Capix.
While those cap style hardhats
are pretty sick, they do jack shiz to protect your head. No impact denisity foam. Just a few soft inserts and a plastic shell.
The correct labeling is a hardhat. They are not meant to take blows and are hardly meant to protect your head at all. Strictly for looks.
Just be warned. Highly recommend investing in a real helmet.
