Oakley Gascan Sunglasses boast two lenses cut from the curve of a single lens shield, then mounted in the frame to maintain the original, continuous contour. The Oakley Gascan shown here is the Special Edition Bob Burnquist Signature. This Gascan is made from excess materials that come from the manufacture of other eyewear, and the eco-conscious design utilizes bamboo for the icon accents and included storage bag. We even made the packaging from recycled materials and soy-based ink.
