They are sealed pretty damn tight. No wind intrusion whatsoever. Sleeping bag battery lasted about 6hrs. Then it got a bit nippy. I knew the forecast but its been a long time since i felt 20 degrees for a long period of time. Colder than i remember 😂. I will do it some more but not at 20. 40-45 would be about right.
