Doug Tompkins and Susie Tompkins Buell founded STONE ISLAND 91270 Backpack 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 kids enthusiasts and urban rockstud alike. STONE ISLAND 91270 Backpack's appeal lies in its blend of durable, high-performance gear with a strong aesthetic appeal, satchel through collaborations with fashion brands such as Supreme and Gucci, as well as its commitment to sustainability and exploration.
