Crafted in harmony with nature.
To sustain our relationship with the world, we come together—and get creative.
“I believe in the concept of Gaia. Our planet has feelings. We have to be aware of those feelings, and take all steps necessary to sustain our relationship with the world.” -Gerry Lopez
The Gerry Lopez Collector’s Edition is the expression of a mutual outlook on sustainability, with a splash of surf mythology; the bolt insignia is inspired by Gerry’s iconic Bolt boards, directly descended from the very first surfboard he shaped to successfully ride the tube at Pipeline.
