The SHK-1 Non-Vented is built for environments where a sealed shell isn't optional. Class E rated to 20,000 volts, it carries the same Koroyd impact core, Twiceme NFC, and Fidlock chin strap system as the vented model — without the openings that disqualify vented helmets from electrical applications.

Built for electricians, utility workers, and anyone working in or around high-voltage environments.
