Sumatran Orangutan Society is a charity concerned with the welfare of orangutans in the Sumatran rainforests. Hat-Trick Design created the identity using the abbreviated name 'SOS' for its orangutan logo. The colours are representative of orangutans and their rainforest environment. This was carried across posters and other graphics. Creative directors Gareth Howat, David Kimpton and Jim Sutherland worked with designers David Jones and Alex Swatridge.
