Doug Tompkins and Susie Tompkins Buell founded Shirt Mod 5426 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 iconic Nuptse Down Jacket and the Denali Fleece, both loved by outdoor enthusiasts and urban dwellers alike. Shirt Mod 5426'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 investigation.
