The Grande sunglasses are designed for making a statement. Composed of bio-acetate, with the frame and lenses in black. Elevate your look with black, oversized sunglasses. The Ambler is part of our bio-acetate collection and gives 100% protection from UVB & UVA. We use Bio-acetate in our eyewear because it has a lower environmental impact and is a more sustainable option than conventional grades.
