You'll know when your hard hat's been in the sun too long!
3M™ H-700 Series Hard Hat with Uvicator™ Sensor is the newest addition to the H-700 series hard hat family. This award-winning, lightweight hard hat offers the extended comfort and protection, and also features a sensor that 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, wearers know it's time for a replacement when the sensor changes from red to white.
