I wear a hardhat everyday, required on all job sites around here, especially mines. I prefer just the front bill, have never owned and not many around here use full bills around. The light on the front is essential, I work afternoons, so most of my shift is in the dark, and a light on your hat is a plus. If you forget your flashlight in the car or job trailer an easy accessible head light is nice. Must turn on and off, and preferably battery powered whether it be chargable batteries or disposable. The second best feature would be some sort of reflective measures on it, currently all of our workers(well not all, some don't care) piece DOT tape around the helmet ~1" pieces around the helmet as well a piece right on the top. I would like something that is part of the helmet that will cover the ears in the winter, and also the back of the neck/hair to keep some what clean from dust.
