3M H-809R-UV FULL BRIM HHAT, HI-VIS

3M™ H-800R-UV series full brim hard hat with UVicator™ sensor and ratchet system is comfortable, tough and lightweight protective headgear that helps protect the head from small falling objects and fixed objects that may be bumped into. This hard hat comes with a UVicator™ 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, the hard hat should be replaced when the sun smart sensor changes from red to white.
