Costa C-Line Adjustable Retainer

The C-Line Adjustable Retainer by Costa is made from a thin but durable wire (corrosion free). The advantage in comparison to many other solutions is, that this retainer doesn't lay on your neck but still keeps your precious polarized sunglasses secured. The length of the Retainer is adjustable and the rubber connectors fit frames of different kinds.

 

Delivered without polarized glasses.
