Greenpeace activists at the Oslo Skifestival with a banner reading "There is no bad weather, only bad clothing. Stop using harmful chemicals!"

The activists are protesting to draw attention to the discovery of PFC (Poly- and per-fluorinated compounds) chemicals present in outdoor 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, including The North Face, Norrøna and Haglöfs. The companies continue to use PFCs to make their gear waterproof, despite their claims of sustainability and love for nature.
