Our current 9772 frame which served as the base for Crossbones is currently one of our bestselling models, originating from a style group that was first created in 1985. The 925 Sterling Silver crossbones detailing, taken from The Great Frog's logo, sits on the redesigned temple which is thickened at the hinge for both a bolder silhouette and improved stability. The slightly larger lens size makes this a great everyday sunglass with attitude in abundance. See our Cutler and Gross x The Great Frog campaign fronted by legendary punk rock musician, Iggy Pop, here.
