The Lochsa frame is the Proof take on the wrap frame. The large temple designs complement the silhouette and the shaping keeps the extra sun out of your eyes. They are 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 effects of deforestation. With each frame purchased, five trees are planted.
