Yulex® Natural Rubber

In 2016 we switched to neoprene-free Yulex® natural rubber because neoprene is environmentally damaging.


Surfers have been hooked on neoprene—the base material for wetsuits—since the 1950s. But it’s a nonrenewable material with an energy-intensive manufacturing process. Developed by DuPont in 1930, it was initially made by chlorinating and polymerizing butadiene, a petrochemical derived from crude oil In recent decades, some companies have used limestone as an alternative neoprene ingredient, but it’s not much better, as it’s another nonrenewable material that’s difficult and damaging to extract. After it’s mined, it’s crushed and superheated in furnaces to over 3,600°F, a process that requires massive amounts of energy.

When we started making wetsuits in 2008, part of the purpose was to develop a less-harmful alternative to neoprene. First, we incorporated natural derived from the guayule plant. A few years later, we completely eliminated neoprene from our suits by using natural rubber tapped from hevea trees. Our renewable Yulex® natural rubber* performs just as well as conventional neoprene, and it’s a far better choice for the planet. While neoprene is made in factories, natural rubber is produced in hevea trees that absorb carbon throughout their lifespan—reducing CO2 emissions by up to 80% in the manufacturing process.

*Made from 85% natural rubber blended with 15% synthetic rubber for additional durability and UV resistance.

Where We Are

In 2016, we were the first surf company to go neoprene-free. Yulex® natural rubber is now the base polymer for all of our men’s, women’s and kids’ suits as well as our gloves, booties and hoods.

But natural rubber can have nasty environmental consequences, too—hevea is a cash crop in many tropical countries, and to plant more of it, rainforests have been slashed and burned, waterways drained and diverted, and toxic defoliants used to remove native ground cover. In Southeast Asia, an area of native forest equivalent to 42 “Manhattans” was converted to hevea cultivation between 2005 and 2015.

When we decided to switch to natural rubber, we wanted to make sure we weren’t contributing to deforestation, so we partnered with the Forest Stewardship Council® to ensure that our hevea was sourced only from plantations that preserve biodiversity and ecological integrity. All of our Yulex natural rubber is FSC certified, ensuring that it doesn’t come from newly clear-cut rainforest, like some of the world’s supply. The Rainforest Alliance—an international nonprofit dedicated to the conservation of biodiversity and sustainable livelihoods—performs audits to confirm that our source plantations adhere to the FSC’s standards on the ground.

What’s Next

Back when we were working with guayule rubber, we ran ads with a slightly cryptic headline: “We have the best weed in town, and we’re giving it away.”

In the small print, we explained we were sharing our Yulex® technology with the rest of the industry in the hopes that other companies would join us in the shift away from neoprene. We kept up that call when we shifted to hevea rubber, and we’re happy that several other surf companies are now incorporating it into their suits. For us, it’s not about a business advantage—it’s about changing the whole surf industry for the better.

From our perspective, however, the best thing about Yulex® natural rubber is that it means we no longer have to choose between performance and the planet. How a suit works in the water—and how long it holds up to everyday use—is still the most important thing, and we’ve been working to make our rubber as light, strong and stretchy as possible. As we look to the future, we hope to further maximize its performance potential while continuing to encourage surfers, and other surf brands, to make neoprene a thing of the past.
