Review on 3M Hard Hat: Unparalleled Protection and Durability for Ultimate Safety by Robert Hole

Poorly constructed to the point of danger. It doesn't want to stay on my head and sits too high. I work for the city water department and often have to work in ditches to fix broken water pipes. These trenches are narrow and I often have to bend down or crouch to make repairs. The helmet sits so high that it 1) does not protect the sides and back of the head and 2) when flexed, rubs against the trench wall and throws debris into the work area. The suspension is cheaply built and I'm also not a fan of the ratchet they use. Another big problem is that I look so stupid that the machine operator laughs at me too hard to concentrate, which is another danger. I'm sure it will provide adequate protection against an object falling directly on your head from above, but my needs are more dynamic.
