3M™ SecureFit™ X5000 Series Safety Helmets provide workers with a comfortable, secure fit that's ideal for a variety of applications. Climbing helmet-inspired, brimless design with chin strap meets occupational safety requirements while helping the wearer maintain greater situational awareness by delivering an obstruction-free field of vision. Low-sitting suspension system minimizes pressure to the head, while its exclusive, patented Pressure Diffusion Technology allows the system to self-adjust to the wearer as the smooth, easy-turning ratchet is tightened. Multiple levels of height and head-shape adjustments allow the wearer to customize the fit even further. X5000 Series helmets meet ANSI safety compliance standards and are designed to protect the wearer's head from small falling objects. All helmets are compatible with a variety of 3M™ face-shields, earmuffs and additional accessories (all sold separately). Vented—Air-circulation vents along the helmet's crown help keep workers cool in warm-weather environments. Hard Hat Style: No-Brim Safety Helmet; Material(s): Acrylonitrile Butadiene Styrene (ABS); Adjusting Method: Pressure Diffusion Ratchet; Suspension: 6-Point.
