SHK-1 Standard Brim Non-Vented

The STUDSON SHK-1 Non-Vented Safety Helmet is engineered for high-risk job sites where maximum protection and reliability are essential. Built with advanced materials and inspired by modern safety technology, this helmet delivers Type II protection—helping reduce impact forces from the top, sides, front, and rear.

At the core is Koroyd® energy-absorbing technology, designed to crumple on impact and dissipate force more effectively than traditional foam systems. The non-vented shell provides the insulation required for electrical environments, while the Class E rating protects against up to 20,000 volts.

Integrated Twiceme® NFC technology allows first responders to access critical medical and emergency information instantly, and the Fidlock® magnetic chinstrap ensures fast, secure use—even with gloves. Lightweight and fully adjustable, the SHK-1 is built for all-day comfort without compromising safety.
