The Outdoor Swimming Society (The OSS) was established in 2006 to pioneer outdoor swimming in rivers, lakes, lido and seas. Led by Founder Kate Rew, The OSS has spearheaded significant cultural change in the way outdoor swimming is viewed and the number of people who take part in it. Full of doers, thinkers and creatives, The OSS team uses its talents and personal time to drive change. They remain a volunteer society and do not charge membership.
