Has anyone used this in heavy rain with a down sleeping bag? I'm worried about opening the mesh footbox to let condensation out in a driving rainstorm
I haven't used this in a rainstorm but I can be pretty sure that if you open the mesh footbox in a rainstorm you're going to get wet.
The waterproof overlap on the foot vent is quite sufficient to keep your bag dry. The Advanced bivy is a bit larger than the Alpine Bivy and feels a more spacious. (for a bivy!)
