The Caldera frame is a fun and explosive shaped frame, just like its name.  Solid aluminum construction & flashy lenses give it a one-of-a-kind look that is sure to call attention. It has a hexagon-shaped design with thin metal lines to complement the lenses.

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.
