Our best selling Dipsea round frame is named after our favorite San Francisco Bay Area hiking trail because it blends the style of the city with the spirit of the outdoors. With a variety of finishes and colorways to suite every occasion, the Dipsea is an updated take on a classic round shape. SuperLight is created from scrap plastic that would otherwise end up in a USA landfill. They intercept this scrap plastic from the waste stream and reformulate it into their SuperLight polycarbonate resin.
