As the review by D. King says below, the vestibule is what drew me to this particular tent. In addition, the complete screen style of the tent when not using the rainfly is awesome. You'll also find many others describing the "coziness" if your tenting with two people. My advice, buy this tent if you want to go camping with someone you don't mind getting cozy with! Durable, warm, well-ventilated. A bit on the heavy side to carry by one person, but it's doable. After two days of schlepping it by myself, I had to forfeit some of the load to a fellow hiker. All that being said, still very glad I decided to go with this tent and would buy it again if given the chance.
