The key is dressing for it. On my bed are all the things I wore over standard underwear. Having recently lost weight simplified things, since I had several sizes to hand.
aqua wool blend compression socks underneath
pink wool blend ski socks inside
Keen "40 below" tan insulated boots
red wool long underwear underneath
gray wool flannel, poly lined trousers
orange cotton long sleeve crew neck underneath
black wool long sleeve crew neck "base layer" underneath
gray wool-acrylic crew neck sweater
very light weight black polypro balaclava underneath
purple microfleece tube gaiter underneath
ink blue faux fur hunter hat with ear & neck flaps down
windblock pink fleece butt length coat with integral hood pulled over my head underneath
black leather knee length cape
What I didn't wear: my glasses--my viewport was only 8 inches wide by 2 inches high, and they'd be immediately frosted.
