Patagonia has partnered with clean technology company Yulex Corporation to create a wetsuit material made from plant-based renewable biorubber, the world's first alternative to traditional fossil-based neoprene. By nature of its production, neoprene is the most environmentally harmful part of creating a wetsuit. For years, Patagonia has looked at ways of cutting down on the amount of neoprene used in their wetsuits. The company has now found a viable solution.
