In some designs it is a small, low tunnel just large enough to hold a pair of boots; in others, it is a full-height standing lobby where you can cook, pack, or wait out a storm. Understanding what a vestibule actually does, and what it does not do, is the difference between gear that performs and gear that fails at exactly the wrong moment.
