GE Super Vent Climbing Helmet with Koroyd
Available in 8 Colors
The GE Super Vent is an award winning safety helmet featuring Koroyd’s advanced impact absorbing technology as the inside protective layer between the ABS shell of the helmet and the head of the user. In comparison with the rest of the safety helmets on the market today, the GH400 is the only one that uses Koroyd's patented technology, as the solely protective material, instead of the traditional EPS foam that most helmets use.
This Type 1, Class C helmet is certified to ANSI Z89.1-2014, engineered for tree workers who need all-day impact protection without sacrificing breathability or comfort. Its defining advantage is the exclusive use of Koroyd® impact-absorbing technology which outperforms traditional EPS foam by 48% while preventing energy rebound onto the wearer.
Optional SENA installation: Please allow 1 - 3 days to complete and ship.
- Unit will be installed "Mic in Muff" with the included 3M muffs.
- If you prefer standard mic location, please mention it in your order comments. We do not recommend this way as broken wires are not covered under warranty.
Details
- Koroyd® liner, not EPS foam: absorbs impact energy 48% more effectively than conventional foam and eliminates energy rebound onto the user
- Cross ventilation system with 10 vents: air flows consistently through the helmet, channeling heat away from the head and reducing heat stress
- 360° adjustable ratchet fit system: a rubber-wheel dial moves up, down, and around to dial in an exact fit across head sizes
- Ergonomic cradle wings support the back of the neck and can be moved inward or outward.
- 4-point adjustable chin strap: black polyester construction with side adjustment points
- Antimicrobial wicking memory foam sweat-band: manages moisture and maintains comfort during full-shift wear
- 10 accessory slots + integrated 4-point clips: front, rear, and side slots accommodate flashlights, eye shields, full face visors, cap-mounted earmuffs (3 cm slots), ID holder, goggles, and headlamps — no separate adapters needed.
Why choose Koroyd over traditional EPS foam?
Because when EPS foam is compressed during an impact, it becomes stiffer, resulting in more energy being transferred from the impact to the head of the user. The Koroyd material used in the GH400 crumples consistently during the impact. This advantage reduces the energy from an impact transferred to the user, and consequently protects the user better.
The mission is to deliver a helmet that offers better protection without compromising user comfort. A helmet so lightweight and compact it's easy to forget it's on, reducing short-term removal and the risk of injury, while improving performance.
The engineered structure of the Koroyd material has many benefits. The most important one is the ability to absorb the energy of any impact at a constant rate, decreasing the chances of injury for the user. Koroyd outperforms EPS foam by 48%, featuring advanced impact technology.
Another vital benefit is minimal heat accumulation. The structure of the Koroyd material is composed by the world’s thinnest walled tubes. This enables heat from the user’s head to vent out of the helmet easily. Helped by the cross ventilation system, the GH400 prevents heat stress in most conditions.
Featuring the world’s thinnest walled tubes, Koroyd's structure is 95% air, providing reduced weight and enhanced comfort without compromising on safety.
