Here is the
link to the AMC Winter Hiking and Backpacking Program starting on November 18:
All good advice but get some training and a good book on winter backpacking. The ADK has good workshops and the Boy Scouts has an excelent program.
I don't like to take off my wet stuff right away, except for my hat & gloves, because it will freez and never dry out. I put on more layers until my body heat takes most of the moisture out and then put them under my pads for the night, sometimes I sleep with them for more insulation. If they freez I wear them on top of my dry stuff until they are warm and switch around layers to suit my comfort level.
I keep dry stuff to sleep in and sleep with a warm water bottle(s). I also have something to drink as soon as I wake up. My boots are still waterproof so I don't get wet that way. I do loosen up my boot laces as much as possible so moisture vent out as I go about my chors.
Dry socks in a plastic bag in wet boots! The produce dept is a great source of plastic bags and the price is right. They don't weigh much so it's easy to pack away a few. Food service type gloves make a good layer for gloves and mittens as well.
I always have an extry dry layer of everything (hat, socks, gloves, long underware, turtle neck) in a garbage bag so no matter what I can walk out dry or be ready fo an emergency.
I like the quiet of a winter nite, it's wind down time from the work week for me. A little snow cover reflects light well and I have a candle lantern that gives off a lot of light as my night vision adjusts.
A little spirits with friends raises the spirits for me.
After or while setting up camp. Hot spices takes meals up a notch or two and warms ths soul.
10 hours in the sack is no problem for me. Try meditating.
FYI I haven't camped in sub zeros yet but I plan for it if it happens.
Booties are on my equipment shopping list.
