Greenpeace activists and volunteers protest in Russia as part of a global week of action around the world to ask leading outdoor brands to stop using hazardous chemicals in their products. PFCs are hazardous and persistent chemicals, dangerous to human health and the environment, and they have been found in the products of brands like The North Face, Patagonia, Mammut, Columbia and Haglofs. These brands keep using PFCs to make their gear waterproof despite their claims of sustainability and love for nature.
