Just looking for a reality check. My gear is 3 season, the bag is rated to 30 degrees and my liner will add another 15 degrees of comfort. I'll be doing the AT NOBO in March of 2020 so in preparation I'll hang here in Rock Island, IL in all sorts of weather to get the feel of 'it all'. With the wind chill temps. can get to 15 or 20 below zero.

Common sense (for a seasoned hanger) would dictate - too cold! I don't have that yet

Thanks,
