The Caldera Aluminum sunglasses by Proof Eyewear are handcrafted from recycled aluminum and cotton based acetate to deliver an ultra-sustainable, albeit super trendy pair of shades. The hexagon, lightweight aluminum frames offer a unique aesthetic and feel to separate you from the aviator and wayfarers of the world, and the lens are incredibly functional with polarized, anti-reflective properties.

Proof’s Caldera Aluminum sunnies are the confluence of innovation, sustainability, and function. Not only will you look good rocking these sunglasses, but they are sourced from upcycled aluminum, which has minimal impact on the environment.
