The 3M Ventilated Safety Helmet is designed for use in harsh environments, with excellent ventilation and a good field of vision. 3M Uvicator sensor disc tells you when your hard hat has been over exposed to UV-radiation and when it is time to replace it. The helet has a softly rounded design that helps avoid parts snagging on cables or branches. Ventilation holes distributed over a large area offer maximum through-flow of air, increasing wearer comfort. The head harness can be rotated 180 degrees for better visibility when working in confined spaces while the short peak gives improved upwards visibility. Suitable for industrial and forestry workers.
