Au contraire. It's worse than you can imagine. When I was 8, I went to the 85 Bears first round playoff game against the Giants at Soldier Field. It was 30 below that day. Look at the man I became. You're fucked.
1) Thermal insulated long underwear
2) Layers
3) Ski mask (this is very important)
4) Probably a scarf to go around the neck
5) A ski cap to put on the ski mask
6) Insulated gloves
7) Insulated socks x 3 or 4
8) Ski boots
9) Thermos full of something hot as hell to sip on
Enjoy the game!
