It’s going to take a highly innovative and unique solution to completely solve the DWR environmental problem. Realizing this, Patagonia turned to the Berkeley-Haas Center for Responsible Business for help. In a student competition run throughout the 2015-2106 school year, Patagonia posed a challenge to 74 different teams, including MBAs and PhDs from some of the best schools in the country–produce an alternative durable water repellent (DWR), strong enough for torrential rains and durable for years, that does not rely on toxic chemicals known as perfluorinated compounds or PFCs.
