Kuntal Joisher is a mountaineer based in Mumbai, India. On 15 May 2018, he stood on top of Mt. Lhotse, the fourth highest mountain in the world at 8516 meters, and became the first in the world to have ascended any 8000 meter mountain on a 100% vegan lifestyle. During the course of the expedition, Joisher only consumed strictly vegan food, and used only vegan gear including a one-piece synthetic suit made completely from animal-free material, as well as mittens and gloves constructed devoid of down or leather.
