Biker accessories label Les Ateliers Ruby have collaborated with Maison Martin Margiela for the third season of their limited edition Signature Program. In the midst of celebrating it's 20th birthday, Maison Martin Margiela became highly enthusiastic about the project to transform the Ruby helmet. Martin Margiela and his colleagues at 163 Rue St-Maur took the programme title literally and each one placed his signature on the helmet to create a collective work. There were only 600 of these very special helmets ever made
