3M™ Hard Hat with Uvicator 4-Point Ratchet Suspension H-704V-UV, Vented, Green, 20 EA/Case

The UVicator sensor changes color as the hard hat is exposed to UV light. The sun’s UV rays can cause a hard hat shell to become brittle and compromise its ability to protect the wearer. With the UVicator sensor, the hard hat should be replaced when the sun-smart sensor changes from red to white. Vents built into the hard hat release heat buildup and allow air circulation to enhance comfort of the worker. The cooling effect of air circulation helps reduce perspiration in hot and humid working environments. A 4-point ratchet suspension adjusts easily to allow for a customized height and fit that best suits the individual who wears the hard hat. The ratchet system allows tightening or loosening the fit without taking the hard hat off.
