Safety helmet for wider range of head sizes

30 September 2025

KASK HAS introduced Zenith X MAX, which the company says is the only safety helmet that extends the fit range up to 66 cm, ensuring a secure and comfortable fit for a wider range of users while maintaining the same high level of protection KASK is known for.

 Currently, traditional head protection maxes out at 63 cm, leaving many workers without a safe and comfortable fit.

“KASK identified a gap in the market for a safety helmet that accommodates a broader range of head sizes. Industry feedback highlighted that many workers struggled to find a properly fitting EN 397- compliant helmet” - said Alex Dabelstein, Global Head of Sales of KASK Safety. “With a design based on real-world biometric research, KASK created a helmet that ensures a comfortable fit and safety to all workers.”

The new Zenith X MAX, an addition to the Zenith X Series, is made with a longer chinstrap and larger internal and external shells, accommodating longer faces and head sizes up to 66 cm, ensuring the maximum protection and comfort for everyone - everywhere. 

Technical details

The Zenith X MAX is compliant with the European safety standards for industrial helmets EN 397, EN 50365 (closed shell only) and it still meets the same clauses of EN 12492 of Zenith X Series.

The Series is available with a closed shell for electrical risk applications (Zenith X MAX) and vented (Zenith X MAX Air) for non-electrical shock applications and in a wide range of hi-visibility and standard colors.

The external shell is made of HD Polypropylene that guarantees impact resistance, high penetration protection and resistance to color degradation, wear and tear. 

The internal shell is comprised of 2 separated patented elements: a lightweight core, called D-Core Technology, and higher density outer cage, called HD Crown Protection – these provide greater all-around impact absorption. The internal shell is made of Neopor Ccycled EPS by BASF, an EPS obtained from chemical recycling of plastic waste and with a reduced carbon footprint, ensuring the same high quality, performance and safety as EPS made from fossil raw material.

Wearer comfort is improved with a multi-directional Adaptive Fit System with a central wheel and a self-adapting neck support. The system provides a quick and easy fit, even with gloved hands, a greater stability on any head shape and accommodates a wide range of head sizes from 60 to 66 cm.

The advanced chinstrap offers a personalized fit with 5 adjustment points and an extra length for a more accommodating fit. 

Like all KASK helmet collections, Zenith X MAX can be equipped with KASK eye, face, and hearing protections, as well as badge holders and weather protections, thus guaranteeing a wide range of configurations and allowing for easy customisation.
