Vestibule

A vestibule is a covered area or extension that attaches to the entrance of a tent, creating additional protected space outside the main sleeping area. It provides shelter for gear storage, cooking, and entry/exit activities while keeping mud, wet boots, and equipment out of the tent's interior. Vestibules are typically made from the same waterproof materials as the tent fly and can be built-in features or separate attachments that extend the tent's footprint.
