Amy V.wrote a review of Black Diamond Bipod Bivy on February 12, 2016
Familiarity: I've used it several times
I brought this sack up with me for some early winter camping . First night was around -6F, second night was closer to 8F. I was plenty warm.
I'm a smaller person so I was able pull my medium sized dog to sleep in the head space with me.
Even with the two of us breathing into the thing for two nights the condensation was minimal.
Good product, couldn't have gone without it.
