The domain, which has been registered since 1996, has now changed registrars and updated WHOIS information and appears to be for sale. The exact price of the transaction was not disclosed.
Currently, HardHats.com has been moved to Namecheap from Tucows, the domain registrar formerly used by First Place® Internet, Inc. and the WHOIS record is private.
The word “HardHats” means “Safety Hats” in Chinese.

What is a safety helmet?
A helmet is a protective headgear used in industrial and construction environments to protect the head from falling objects, debris or impact. Safety helmets are usually made of durable materials such as high-density polyethylene or fiberglass, and are designed with an internal suspension system to effectively absorb impact.
Additionally, helmets are often equipped with accessory ports that allow for the installation of accessories such as face shields, ear muffs, or lights. In potentially dangerous work environments such as construction, manufacturing, and mining, helmets are an important piece of equipment for ensuring worker safety.
Currently, HardHats.com is not resolving, but this may change soon as the domain uses Cloudflare DNS which can be turned on or off.
