Ötzi, also called The Iceman, is the natural mummy of a man who lived between 3350 and 3105 BC. Ötzi's remains were discovered on 19 September 1991, in the Ötztal Alps (hence the nickname "Ötzi", German: [œtsi]) at the Austria–Italy border. He is Europe's oldest known natural human mummy, offering an unprecedented view of Chalcolithic (Copper Age) Europeans.
kinda looks like there's no ass cover on those chaps he's wearing, i guess that's the secret to the paleo diet
So i actually looked this up and it seems he wore assless goat chaps and a sheepskin loincloth. The reconstruction doesn't show it, but he also wore a hat made out of bear fur and a leather coat with some kind of liner made of grass underneath. Dude was way up in the mountains, had to keep his butt from freezing off somehow.
