Founded in 2014 by a team of engineers and designers from the Italian automotive industry, 6D entered the motorcycle helmet market with a radical departure from traditional sizing. Unlike standard helmets that rely on generic size categories (S, M, L), 6D pioneered the use of 3D scanning technology to capture the precise geometry of an individual's head. This data is then used to manufacture a custom-fit shell and liner system designed to eliminate pressure points and maximize comfort without sacrificing safety standards like ECE 22.06 or Snell. Their entry into the market was driven by the belief that a perfect fit is the foundation of both rider comfort and optimal crash protection, positioning them as a high-performance alternative to mass-produced brands.
