The Esker frame is another Proof take on the classic aviator. The larger silhouette and retro shaping are complemented by its unique cut-out detail above the bridge of the nose. Designed for those who want a durable and sustainable construction frame that embodies a bold style.

Extreme attention to detail is placed in each frame and every style features a unique laser engraved quote on the inside arm.  Every frame purchase comes standard with a folding cork case and microfiber cloth to protect and clean your frames.

Proof has been pioneering sustainable eyewear from the beginning and is committed to making a positive impact through our Do Good initiatives in our local & global communities. We are proud to partner with the Eden Reforestation project to help combat the impacts of deforestation. With each frame purchased, five trees are planted.
