World's Fastest Sweatshirt?

Spotted on Triumph's Official facebook page, Guy Martin out on Bonneville Salt Flats, testing the Triumph Rocket streamliner while wearing a Sideburn Engine sweatshirt. The photos are from the first day of practice, with the stabilisers on. They didn't stay on for long. The bloke's a natural.
