Black Yak is a Korean company created by Tae Sun Kang back in 1973, after he noticed how much Koreans were lacking good mountaineering equipment. The yak is a powerful animal, indispensable during Himalayan expeditions, and is known as the Sherpa of Sherpas amongst experienced mountain climbers. Black Yak products seek to be just as valuable a companion to mountaineers as the yaks.
