If you kids would take a break from peeing in each other, I have a dumb question I'd like to ask.
What exactly is a bivy bag, what does it do and what is a "good" one vs junk?
and while you are answering that question, what, in your experience, is the best thing to wear while sleeping in a sleeping bag?
I guess it would depend on conditions.
I can tell you what works for me in moderately cold weather, meaning down to low 20's.
I wear clean merino base layers and clean merino socks. I sometimes stuff a down vest in my bag for next morning.
I believe this would take me comfortably down into the teens though in my area, or the time of year I go out west, it would be an anomaly for the temps to drop that low.
Guys routinely experiencing more extreme conditions would likely laugh at this but living down south that's just our conditions.
Those guys who have experience in extreme conditions need to chime in.
