I'm visiting my Daughter and Grandchildren in Indiana. Mostly in the 40's and 50's with intermittent rain. Breezy. One day freezing my arse off and getting wet was enough. This Pod is awesome. I have an electric blanket and it is more than enough, just the heat it is putting off keeps the inside warm. I think with the electric blanket, this thing would make things tolerable down in the 20's. I got the next one up from the smallest and I'm glad I did. If I lived where this was a permanent solution, I'd opt for the two person model. I think I paid $139, very reasonable for comfortable smoking in the cold. Folds up very compact, would also work nicely for watching kids sports when the weather is a bit bad.
