Biker accessories label Les Ateliers Ruby have collaborated with Maison Martin Margiela for the third season of their limited edition Signature Program. Margiela have produced a crash helmet signed by every member of their team; the carbon fibre filter is unevenly painted white for the signature ‘meudon white’ effect that Margiela’s known for. The helmet interior is plush black and the brand logo is on silver. In very limited numbers, Oki-ni are releasing the helmut on their site tomorrow and will be available for £699 each.
