The S-Lock 18mm belt was inspired by the iconic Petite Malle handbag, created by Artistic Director Nicolas Ghesquière. Its reversible strap offers a choice of sleek calfskin or Monogram canvas for an unmistakable House look. But its centerpiece is a striking trunk-style S-Lock buckle, engraved with the LV Circle emblem and a Louis Vuitton Paris signature.
