The Skullerz 8974LED Class E (Electrical) Safety Helmet features a dielectric shell and a six-point suspension system to provide heavy-duty, yet lightweight and comfortable, all-over-head protection from top, side, front and back impacts as well as high-voltage system contacts. Its smaller, low-profile brim helps improve overall field of vision, particularly when looking up, and patent-pending headlamp slots on the front and rear of the exterior accommodate Skullerz Hard Hat Headlamps. One Skullerz 8981 Universal LED Headlamp is included to help you keep your path and the object of your attention illuminated. The helmet's flexible, open-frame, multi-point adjustable-suspension design maximizes airflow for breathable, all-day wearing comfort, and a one-size-fits-most format accommodates those who wear hat sizes 6.5 through 8. A premium, easy-adjust ratcheting system allows the wearer to tighten or loosen the fit without having to take the helmet off, and its one-handed fit-adjustment knob pivots to improve overall ergonomics while providing extra clearance for bandana or ponytail knots. A padded, moisture-wicking, odor-resistant sweatband and top pad line the sides, forehead and top of the interior, and both the headband and top pad are removable for machine-washing and/or easy replacement. An integrated chin strap allows the wearer to secure the helmet in place to ensure protection during sudden movements, falls and impacts. Built with even weight-distribution and comfort in mind, all Skullerz 8974 helmets should deliver a snug, balanced fit to please nearly anyone. For jobs where increased eye protection is needed, the helmet also accommodates easy, bolt-on mounting of Skullerz Safety Helmet Visors (visors sold separately). From mountain-climbers to miners, from communication-tower technicians to pipefitters... whether you're on top of the world or deep within it, 8974 series safety helmets are designed to help you keep your head.
