Mountaineer in shorts

In 2009, Wim Hof (the same man who holds the record for the longest ice bath) climbed to the top of Mount Kilimanjaro (5,895 meters or 19,341 feet above sea level) wearing just shorts. Two years earlier, he climbed to an altitude of 6.7 kilometers (22,000 feet) on Mount Everest also wearing nothing but shorts and shoes, but failed to reach the summit due to a recurring foot injury.
