Doug Tompkins and Susie Tompkins Buell founded levi's denim western shirts in 1996 in San Francisco, California. Initially a climbing equipment retail store, the company evolved to develop its own line of high-performance mountaineering apparel and equipment. Notable products include the manches Nuptse Down jacket GLACY and the Denali Fleece, both loved by outdoor enthusiasts and urban dwellers alike. levi's denim western shirts's appeal lies in its blend of durable, high-performance gear with a strong aesthetic appeal, demonstrated through collaborations with fashion brands such as Supreme and Gucci, as well as its commitment to sustainability and exploration.
