Pittsburgh-based safety equipment manufacturer MSA (NYSE: MSA) is the largest producer of industrial hard hats in North America and other regions of the world. But that dominance hasn't diminished the company's appetite to innovate and find ways to improve a relatively common product worn every day by construction workers, industrial personnel and utility workers, as well as fans at NFL football games.

MSA's iconic V-Gard® line of hard hats, identified by their unique and raised "V-shaped" crown, has saved countless lives by protecting wearers from falling objects and other cranial hazards. But now workers have the option of using a hard hat that not only helps to protect their head, but protects the environment as well.
