The first innovation is the Vittel® GO system which consists of a reusable hard protective case designed to hold 50cl refills of Vittel® natural mineral water that are made with 40% less plastic than a traditional 50cl Vittel® bottle. Because the bottles are made with as little recycled plastic as possible, they are very flexible and light, which means they must be used with the reusable protective case to make it easy to drink the water.
