What do you wear on Mount Everest?
Below 23,000 ft they wear Plastic boots with booties so they can
dry them. For the hands they have glove shells and insullated inner
gloves. For the torso, 3 layers, 1st is a tight fitting long
underwear, 2nd a fleece or syntheric isulater layer, 3rd down jaket
and snow pants. In bad weather they put on a outer shell, you would
recognize all the cool patches and such. Above 30,000 ft it is a
full down snow suit and mitten instean of gloves for extra
warmth...
Hope that gives you a better idea..
