Greenpeace activists climbed to the top of the Xinantecatl volcano, 4200 meters above sea level, in Toluca, State of Mexico. At the summit, activists unfurled a banner denouncing the use of hazardous chemicals in the manufacture of outdoor gear and clothing.

A new Greenpeace report reveals that hazardous and persistent chemicals, dangerous to human health and the environment, have been found in the products of leading outdoor brands. The companies continue to use PFCs to make their gear waterproof, despite their claims of sustainability and love for nature.
