The agency, which triumphed in a final shoot-out against McCann Erickson Manchester and The Leith Agency, has been briefed to deliver a summer brand idea to drive awareness of Barbour's expanding clothing range among over-25s who participate in country sports.
The endline "fit for purpose" will be retained as the driving force behind the campaign. The work will attempt to raise the company's profile in Barbour's main markets; the UK, Germany and the US.
Claire Saunders, the marketing director at Barbour, said: "We were looking to work with a partner agency that could not only offer us a quality of creative thinking but could also adapt the Barbour voice. Quiet Storm demonstrated ably that it could do both."
Media will continue to be handled by Purely Media in Manchester.
