Woke up at 6am, slept through the night just fine without waking at all. Temp readings inside the tent on the wall/ceiling is 41, even though it's frozen. Temp in the grass is 32. Water bottle temp is 92. Pretty comfortable night. Re-entry to bag/s went okay and everything is comfortable right away, except the pillow moved and now a frozen part is right on the back of my neck. So far things went very well.
