What body parts are most vulnerable during camping?

if you meen summer camping then it will be any part of the skin that's shown. it'll get sunburn. if it's the winter than it's the outer extremities (fingers ant toes.) when you start losing body heat you will lose those first and then your hands, feet, arms legs, and your dead. but if you wear the right clothing then you'll be good. i suggest wool or fleece. but don't get iether of them wet your balls
