Karl Lagerfeld is the latest fashion heavyweight to team up with 4 favourite Les Ateliers Ruby for the fourth installment of their limited-edition helmet series.

Following Maison Martin Margiela’s artful defacements, which were stocked by 4, Karl is giving the protective headgear the ultra-luxe makeover. First appearing on Karl’s runway for fall, the creations include a lady-like helmet in black and white tweed (a subtle nod to Chanel) and a couture-ish one embroidered in pearls. But the most obscenely luxurious headdress has to be the one covered in lustrous black mink—part urban barbarian, part futurist warrior!
