The bottom line The Bullard S51R Safety Helmet is the ANSI Z89.1 Type I-compliant hard hat that genuinely lasts 10+ years of regular use. The polyethylene shell resists impact and electrical conduction (Class E rating to 20,000 volts), the FlexGear suspension distributes weight comfortably across the head, the ratchet adjustment fits 6.5-8 inch head sizes, and the Bullard build quality has been the standard for decades. The trade is the price (real money for a hard hat) and a Class E rating that is overkill for non-electrical work.
Value
At $25 the Bullard S51R is the right ANSI-compliant hard hat in 2026.
