Clothing/Shoes/Weather Gear: well if you're around in these temperatures, you should be wearing your whole closet on you :)) the best materials are cotton against the skin in couple of layers, and on that wool clothes, and then the outside clothes with 'thinsulate' or alike. in this picture i am wearing 3 layers of clothes under these outside clothes :)) under your hat its good to have another one in 'commando' style which will protect you inhaling the cold air. after a while outside you will notice that your eyelashes are all covered in ice :))kinda funny when they start melting inside again :)) you'll really feel you've been on an arctic adventure!!!
