I am a Physician Assistant, working in primary and emergency medicine. I fully endorse saline nasal and sinus flushing.

Now that I have that out of the way...

Thanks for sharing your pod experiences. I too have never been miserable cold when winter camping. Seeing your setup, though, helps me with ideas to experiment with. I am curious though, are you able to lay on a diagonal at all in your hammock while in your pod system? I have avoided this layout for fear of the banana lay and a sore back in the morning.
