Watch 2 Athletes Climb K2 Without Supplemental Oxygen

Is K2 the world’s most dangerous mountain? Without oxygen, it definitely could be.

Climbing an 8,000m peak is not for the faint of heart. And last year, mountain guides Carla Perez and Adrian Ballinger successfully summited K2 without supplemental O2.

Summiting these types of peaks without supplemental oxygen is a dangerous endeavor that requires the highest level of focus and safety on the mountain.

This week, Eddie Bauer released a film by Ballinger recapping the expedition, with never-before-seen footage of the pair’s journey up K2.

Ballinger and Perez aimed to summit the 8,611m peak — a feat that landed them in a community of explorers fewer in number than those who have been to outer space.

It’s cold, technical, brutal, demanding, and complicated. But it’s also a beautiful and breathtaking experience.
