Who Are the King Killers?

Built in the Cage, Not a Boardroom.

King Killers is a US-based small business owned and operated by real fighters competing in BJJ, boxing and MMA. It started with Michael “Heck” Heckert — a professional fighter who fell in love with combat sports at local cage fights with his dad.

A “King Killer” hunts the people at the top. That mindset is stitched into every piece we make: premium fightwear at the best possible price, tested by people who actually compete.

“Our goal is to work our way through the rankings until we one day match up against the King.”
