The Boulder is a wooden interpretation of the popular trapezoidal shape, handcrafted & assembled from the finest woods available. The wood used in these frames is sustainably sourced making them environmentally friendly. The Boulder is one of our newest and best-selling frames and it's not surprising because of its classic style and unique look.

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.
