Yes. The KASK Zenith X2 MAX (WHE00134) is a non-vented ANSI Z89.1 Class E helmet, proof tested to 20,000 volts, so it is suitable where electrical hazards are present. It is engineered specifically for larger head sizes, adjusting from 60 to 66 cm, and is certified Type I and Type II for all-around protection against impact and penetration at the front, rear, and sides. It weighs 1.19 lb and comes in nine colors: white, yellow, orange, red, green, blue, anthracite, black, and light grey.

The KASK Zenith X2 MAX WHE00134 meets ANSI Z89.1 Type I, Type II, Class E, HT-LT. Type I covers top impact and Type II adds lateral (side) impact; Class E means electrical protection, and KASK proof tests this model to 20,000 volts; HT-LT means it is tested for high- and low-temperature performance (rated use from -22°F to +140°F). KASK also certifies it to selected clauses of EN 12492 (the European mountaineering helmet standard): front, lateral, and rear shock absorption, penetration, and retention-system strength and effectiveness — signaled by the lime-green chinstrap buckle.

The difference is the size range. The Zenith X2 MAX delivers the same performance and comfort as the original Zenith X2 but with an extended fit range for larger heads, adjustable from 60 to 66 cm. It keeps the same core design: ANSI Z89.1 Type I, Type II, Class E protection proof tested to 20,000 volts, an HD polypropylene shell, a D-Core/HD Crown internal shell, the Adaptive Fit System, and an eco-leather chinstrap redesigned to accommodate wider sizes. Choose the MAX when you need the larger 60–66 cm fit range.

Yes. The non-vented KASK Zenith X2 MAX WHE00134 is ANSI Z89.1 Class E, and KASK proof tests it to 20,000 volts, with an external shell that protects against electrical hazards. Class E is the ANSI rating for electrical work; a Class C (conductive) helmet provides no electrical protection and should not be used where there is electrical exposure.

They are the two layers of the helmet's internal shell. D-Core is a low-density inner core optimized for top-impact protection, while HD Crown is a durable high-density component that provides stronger side-impact absorption and protects the inner core, for all-around defense. The internal shell is made of Neopor® Ccycled® by BASF — an EPS foam obtained from chemical recycling of plastic waste — inside a lightweight HD polypropylene outer shell that excels in impact absorption at temperatures as low as -30°C and resists yellowing and degradation.

It adjusts from 60 to 66 cm with the Adaptive Fit System, which combines three components: a double-diameter dial for easier size adjustment, ergonomic side wings for a secure fit against the back of the head, and KASK's patented Self Adaptive Live Hinge, which moves as the wearer moves. For comfort, the Dry+ liner uses Hydrocool® moisture-wicking fabric with a silver-ion deodorizing treatment, the headband is soft PA nylon, and the Click-In padding snaps in and out for tool-free replacement. The eco-leather chinstrap has rear and lateral adjustment points and adapts to earmuff use; the whole helmet weighs 1.19 lb.

It is designed to be accessorized. The KASK Zenith X2 MAX includes four removable nylon lamp clips compatible with KASK headlamps and industry headlamps with elastic bands, earplug hooks built into the lamp clips, standard 30 mm EURO slots for KASK earmuffs, Easy Click adapters for visors and face shields, and a frontal accessory slot for headlamps or ID badge holders (with a cap cover for debris protection). A Ring to Hook chinstrap loop lets you tether the helmet to a harness, and a high-visibility nameplate on the back allows quick identification.

For impact protection and fit, yes. A traditional hard hat is typically ANSI Z89.1 Type I (top impact only), while the Zenith X2 MAX is certified Type I and Type II, Class E, HT-LT, protecting against impact and penetration from the top, front, rear, and sides while keeping 20,000-volt proof-tested electrical protection. It adds a chinstrap retention system certified to selected clauses of EN 12492, a dual-density D-Core/HD Crown liner, and an extended 60–66 cm size range for larger heads — features a basic hard hat doesn't offer.

Yes.
