Each SHK-1 comes in a standard or full brim shell, and in a vented Class C or non-vented Class E version.
Koroyd is a welded tube structure inside the helmet that crumples instantly and consistently on impact, absorbing force in a controlled way so less energy reaches the head. twICEme is an NFC chip built into the helmet that stores emergency contacts and critical information for first responders.
Koroyd absorbs more energy from any angle of impact, protecting the skull and brain.
Koroyd says its structure outperforms EPS foam by 48% and prevents energy rebound.
Inspecting the tube structure shows when the helmet is compromised and needs replacing.
Air flows through the open cell structure, so hot air escapes from the head.
The tubes are 95% air, so the helmet stays light without giving up protection.
Stores emergency contacts and medical details that responders can read with a phone when seconds matter.
Add eye, face, hearing and sun protection to the helmet, plus comfort items for hot and cold days. For work at the slab edge, pair helmets with debris and safety netting and guarded scaffold platforms.

On construction sites, OSHA 1926.100 requires head protection wherever there is a possible danger of head injury from impact, falling or flying objects, or electrical shock. In general industry, OSHA 1910.135 requires helmets that meet ANSI Z89.1.
ANSI Z89.1 Type I helmets protect against blows to the top of the head. Type II helmets, like the SHK-1, also protect against blows to the sides.
Class E helmets are tested to 20,000 volts under ANSI Z89.1. The non-vented SHK-1 models are Class E.
Class C helmets give no protection from electrical hazards. Vents keep them cooler where electricity is not a risk.
