Surfers have been hooked on neoprene since the 1950s, but it's a nonrenewable material with an energy-intensive manufacturing process. By replacing it with Yulex® natural rubber from sources that are Forest Stewardship Council® certified by the Rainforest Alliance, Patagonia is reducing CO2 emissions by up to ~80% when compared to conventional neoprene-causing less harm to the planet we love and the oceans that give us waves to ride. www.patagonia.com
