Unlike conventional hard hats manufactured from high-density polyethylene (HDPE) sourced from nonrenewable petrochemicals, the V-Gard GREEN hard hat is manufactured using green HDPE sourced entirely from sugar cane ethanol. The hat meets rigorous ANSI Z89.1 and CSA Z94.1 performance standards and is marked with a recycling label to remind users to recycle their helmets at the end of its use cycle. MSA. us.msasafety.com
