Quicksilver are a great brand. They are not a sports company that has moved into the surf market, they are a surfing brand outright. I think they have got the perfect balance of exciting fashion, bright colourful products and still retain a certain amount of street cred. They are edgy, fun and cool. There are very few other brands that have a specific brand image and manage to stay interesting. It is such a natural progression for Quicksilver to move into wetsuit sales, life jackets, sandals, women's summer dresses backpacks as well as their crossover onto skate wear. OP are a massive brand, but they have an unique appeal that few others clothing brands have.
