What is the
point of a
two-way zipper?
Consider, for example, when standing in a winter storm, you are looking for your car keys in the side pocket of your suit jacket or pants. Rather than unzipping your jacket completely, from the top, to reach said pocket, exposing your person utterly to the cold and damp, you need merely pull upwards on your jacket’s lower zipper pull, while remaining comfortably warm and protected!
