Final answer:
Jon Krakauer would likely wear modern mountaineering clothing comparable to Ötzi's ancient outfit, consisting of a technical jacket and pants, insulated boots, a hat, and gloves, carrying it all in a specialized backpack.
Step-by-step explanation:
The type of gear Jon Krakauer would have had on an alpine expedition, similar to the one where Ötzi the Iceman's remains were found, would typically include clothing and equipment designed for extreme cold and rugged terrain. Krakauer, an experienced mountaineer and author of Into the Wild, would likely have worn a modern equivalent to Ötzi’s ancient gear: a technical jacket and pants, a warm hat, gloves, and insulated, waterproof boots. Additionally, such gear would be carried using a mountaineering backpack equipped with straps and compartments for effective weight distribution and accessibility.
