Workers wearing this hard hat will also appreciate its low profile design and balance, which provide for a more comfortable and less obtrusive feel.

The hat may be worn in either the forward or reverse donning position. Hat weighs 12.8 ounces.The rigid shell of the 3M Hard Hat H-700 Series helps reduce chances of injury by deflecting small falling objects from striking the head of the person who wears this safety headgear. The hard hat also helps protect from injuries due to bumping into stationary objects such as pipes, rods, shafts, construction timbers, branches, or exposed electrical conductors. The suspension system inside the hard hat helps absorb the effects of the impact to dissipate the force. Even small objects can cause significant injury due to the force built up from the momentum of falling. Something as small as a washer or coin can strike with the force of several pounds if it falls far enough. 3M hard hats reduce the impact if a strike occurs.
