Gail Thirteen Sun Sunglasses by ProDesign Denmark. Color: 4031, 6031, Size: 46-24-150. Gail Thirteen is the unique combination of artistry and minimalism. It is an opulent mix of two words: the Danish devotion to form and function and the expressive American mentality. The look is modern and retro at the same time. The frame features a simple structure gathering all parts in the iconic cylinder hinge providing a refined, clean look that balances the many strong aluminum colors. Innovative and distinct Gail Thirteen frames are offered in two shapes – half-rim and full-rim (also available in a sunglasses version), and feature unique temple structures that provide the frames with a natural flex and unique expression – but still inspired by the original design.
