A wearable device includes a unitary first frame assembly which is integrally formed from first and second polymeric materials. The first frame assembly has a first frame portion formed by the first polymeric material and extends around part of a second frame portion formed by the second polymeric material. The first frame member includes a flexible first shell and a first connecting portion which depends from the first shell. The second frame portion forms part of the first shell and continuously extends to the first connecting portion without interruption. The second polymeric material has greater rigidity than the first polymeric material. The device also includes a second frame assembly having a second connecting portion which links to the first connecting portion.
