Wetsuits are horrible for the environment. They’re made of neoprene, a petroleum derivative, and the manufacturing of neoprene is extremely toxic for the environment. California clothing company Patagonia has partnered with Yulex, a company who makes plant-based biorubbers, to create a wetsuit made out of mostly plants (60% guayule and 40% neoprene). Patagonia makes their proprietary biorubber available for the whole industry to support the environment while the company is working on a design to make a wetsuit from 100% guayule.
