What the Ergodyne Skullerz 8967 Cap-Style Hard Hat Offers

This is the electrical-rated member of the Skullerz cap-style family. It is certified Type 1, Class E — tested at 20,000 volts — and that rating is the whole point, because it is only possible with a non-vented shell. Vents are openings that cannot be tested as a dielectric barrier, so the solid shell here is not a limitation but the enabling feature. It is the direct counterpart to the vented, Class C Skullerz 8966: nearly the same helmet, opposite side of the electrical line.

Underneath, the shared Skullerz platform: a height-adjustable 6-point suspension with a one-handed LockFit ratchet giving 36 points of adjustment, an HDPE shell about 15% lighter than PC-ABS, and a removable, breathable, washable foam-backed sweatband. It fits hat sizes 6.5 to 8.25, and Ergodyne positions it for construction, utility, oil and gas, road work, forestry, mining and work at height. Compare it across the range in our cap-style guide and overall rankings.

Cooling Without Vents — How a Class E Hat Manages Heat

A non-vented hard hat carries an inherent tension: the solid shell that earns the Class E rating is the same shell that traps heat. The 8967's answer is the flexible open suspension frame. Rather than sealing your head against the inside of the shell, the suspension is built as an open structure that lets air move through the gap between head and shell — so you get some circulation without any openings in the shell itself.

It is worth being honest about what that does and does not achieve. It is a partial measure: an open frame narrows the heat penalty of going non-vented, but it does not match actual vents. The washable sweatband is the other half of the same story, and it matters more here than on a vented hat precisely because this one runs warmer — a fresh, breathable band manages the sweat a non-vented shell holds in. If your work has no electrical hazard, you are not obliged to accept that heat trade at all: the vented 8966 exists for exactly that case, and our electrical hard hat guide covers when the Class E rating is worth it.

Frequently Asked Questions

What makes the 8967 the electrical version?

Its non-vented shell. The 8967 is certified Type 1, Class E, tested at 20,000 volts, and that rating is only possible because the shell has no vents — vents are openings that cannot be tested as a dielectric barrier. It is the direct counterpart to the vented 8966, which is otherwise almost the same helmet but is Class C with no electrical protection. If electrical exposure is a factor in your work, the 8967 is the one to choose.

If it has no vents, how does it stay reasonably cool?

Through the flexible open suspension frame rather than through the shell. The suspension is built as an open frame that lets air move in the space between your head and the shell, so you get some circulation even though the solid shell has no vents. It is an honest partial answer — a non-vented hat runs warmer than a vented one, and the open frame narrows the gap rather than closing it. Where there is no electrical hazard and heat is the enemy, the vented 8966 will still run cooler.

Why does the washable sweatband matter more on this hat?

Because a non-vented shell traps more heat and sweat than a vented one, so the sweatband does more work. The 8967's foam-backed sweatband is removable, breathable and washable — you can pull it out and clean it rather than letting it degrade into the reason the hat gets pushed back on the head. On a warmer-running non-vented helmet, keeping that band fresh is the difference between a hat that gets worn properly and one that does not.

What is the LockFit ratchet and the 36 points of adjustment?

The LockFit ratchet is a one-handed adjustment dial, and the suspension offers 36 points of adjustment across its range — meaning you can dial the fit precisely rather than jumping between coarse notches. Fine adjustment matters on a helmet worn all day, because the difference between firm-and-stable and slightly-too-tight is often one notch, and 36 points lets you land on the right one.

What does the 6-point suspension add over a 4-point?

Force dispersion and comfort. Six suspension points spread both an impact and the static weight of the helmet across more of the head than a 4-point, which most wearers feel as fewer pressure hot spots over a shift. Ergodyne pairs the six points with height adjustment, so you also set how low the helmet sits on your head, not just how tight.

How much lighter is the HDPE shell?

Ergodyne states the high-density polyethylene shell is about 15% lighter than PC-ABS hard hats. Weight compounds over a full shift into neck fatigue, and a lighter hat is one that stays on rather than getting pushed back. The trade with HDPE is that, like every thermoplastic, it is not for high radiant heat or molten metal, which need materials specified for those environments.

Is it Type I or Type II?

Type I — top impact only. Type II adds lateral protection to the front, back and sides, and no cap-style hard hat becomes Type II through suspension quality. If your job hazard analysis specifies Type II, you want a rated Type 2 safety helmet instead; the 8967 is a Type 1 helmet whatever else its specification offers.

Is Class E the same as arc-flash protection?

No, and the distinction is important around electrical work. Class E is a dielectric contact rating — the shell is tested at 20,000 volts against contact with an energized conductor. Arc flash is a different hazard with its own standards and its own rated equipment. A Class E hard hat is not arc-rated, so do not treat the two as interchangeable when specifying PPE for arc-flash boundaries.

How should I decide between the 8967 and the 8966?

On the electrical hazard, first and last. If any part of the work involves electrical exposure — including incidental contact, which is exactly what head protection guards against — you need the non-vented Class E 8967. If there is no electrical hazard and the work is hot, the vented Class C 8966 runs cooler and is the better pick. Everything else about the two is close, so let the hazard assessment make the call.

What work is it built for?

Ergodyne positions it for construction and utility job sites, oil and gas, road work, forestry, mining, general site work and projects at height — a spread that reflects the Class E rating being useful wherever electrical exposure is possible alongside general impact hazards. Utility and line work in particular want both the electrical rating and a lightweight all-day helmet, which is the combination here.

How do I verify the class and the helmet's age?

Read the Type and Class markings molded inside the shell rather than relying on listing text, especially before depending on the Class E rating for electrical work. The date of manufacture is stamped inside too, usually as a clock-face marking the month and year. Retire the helmet after any impact, since a shell can absorb energy without visible damage, and replace it on cracking, chalking or UV brittleness. Suspensions and sweatbands wear faster than shells.

Can I drill it or modify the shell?

Never — and it matters more here than on a non-electrical hat. A single hole compromises impact performance and voids the Class E rating outright, which you may be relying on around live conductors. Keep stickers minimal and off the crown, since they can hide developing cracks and some adhesives attack the plastic, and do not paint the shell because solvents degrade it.
