A thin neoprene face mask will be required to cover the face, along with a thick balaclava.
Clothes: Plastic frost-proof climbing boots, a base layer of thermals and a spare set to change into at night. Five to six pairs of socks for the whole trip. On the mountain, you'll have just two pairs: one to walk in, the other to sleep in. The 'wet' pair, that will absorb a wine-glass capacity of sweat each day per foot, will be dried in your sleeping bag at night. Your first fleece layer will include tight fleece trousers and tops. This first layer needs to dry overnight, to be worn the next day. Your second fleece layer will comprise two thicker fleece jackets and one pair of thicker fleece trousers. You'll also need a down suit, or down trousers and jacket. Two bandanas will protect the neck from sunburn. A thin neoprene face mask will be required to cover the face, along with a thick balaclava. Two fleece hats will cover ears, while a baseball cap with a big visor will protect from the sun. Two pairs of thin gloves for dexterity and several pairs of mountain mitts will keep hands warm. Huge Gore-Tex overmitts will go over all the other pairs of gloves.
