The Skullerz 8975V Class C (Conductive) Safety Helmet with 8991 Visor Kit features a unique, vented shell and a flexible, open-frame, six-point suspension system to provide heavy-duty, yet lightweight and comfortable, all-over-head protection from top, side, front and back impacts. For increased eye and face protection, 8975V helmets also include an easy-mount, removable visor that features a z87 UV-protective lens that's treated with Fog-Off and Tena-Coat technologies. Permanent Fog-Off, anti-fog technology ensures crystal-clear see-through, no matter the job, which is particularly useful for those working with face masks and respirators or those trekking though environments where extreme temperature changes are common. Reliable Tena-Coat technology provides durable scratch-resistance against kicked stones, windblown dust and a variety of other abrasive nuisances. The helmet's adjustable exterior venting allows the wearer to remain cool in hot, dry weather by opening the vents or to remain warm and dry in cold, wet weather by closing the vents, and the compact shell's smaller, low-profile brim helps improve overall field of vision, particularly when looking up. A one-size-fits-most format accommodates those who wear hat sizes 6.5 through 8, and a premium, easy-adjust ratcheting system allows the wearer to tighten or loosen the fit without having to take the helmet off. The rachet system's one-handed adjustment knob also 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 8975 helmets should deliver a snug, balanced fit to please nearly anyone. Patent-pending headlamp slots on the front and rear accommodate Skullerz Hard Hat Headlamps (lamps sold separately). From mountain-climbers to spelunkers, from iron-workers to pipefitters... whether you're on top of the world or deep within it, 8975 series safety helmets are designed to help you keep your head.
