Deb Bolner Prost has built her entire career on helping people and companies market themselves or their products. Now she’s using that expertise to market a new product of her own. For the better part of four years, Prost and her four partners in It's 2 Cool Ltd have been working on a new product they've named Cool Off―a packaged towelette saturated with botanical compounds that produce a strong cooling effect on the user's skin. They call it Cool Off. And this month they plan to roll it out in stores throughout South Texas for the first time.
