The Gogo is not the lightest shelter per square foot of floor space but it is very warm and it allows me to get away with a thinner sleeping bag. I actually like the closed in feeling. Maybe I'm part dog LOL!!! Is there a word for the opposite of claustrophobia? It works well for Sierra summers where temps can dip below freezing in August. It can be configured with a small vestibule....if you're not too tall. I'm 5'10' so it works well for me.

Another big plus for me.......I HATE breaking down camp. But I can pack up the Gogo in under 30 seconds. Just pull out the sleep pad, open the air valve, and roll it up. The sleeping bag stays inside, protected by the waterproof fabric. No need for a stuff sack. The whole thing gets stuffed into the bottom of my pack.
