Wetsuit sustainability

No wetsuit is 100% sustainable

Even the most eco-friendly suit on the market contains synthetic materials in its linings, thread, glue, and accessories. No brand has eliminated oil from the production chain entirely. Natural rubber alternatives like Yulex and OCENA are a meaningful step forward, but they're not the finish line. Keep that in mind when a brand calls their suit "sustainable" without qualification.

Materials: the biggest lever

Natural rubber from hevea trees (Yulex, OCENA) reduces CO₂ emissions by roughly 80% compared to neoprene and comes from renewable, FSC-certified sources. Limestone neoprene is marginally better than petroleum but still synthetic and still requires significant energy to manufacture. Petroleum-based neoprene is the worst option — energy-intensive production, toxic emissions, and a non-renewable resource.

The shift to natural rubber is accelerating. Xcel committed to going fully neoprene-free from Spring 2025. Decathlon launched 100% natural rubber suits (Yulex100). Billabong, needessentials, Patagonia, SRFACE, C-Skins, and others already offer natural rubber lines.

Carbon black and circularity

Carbon black — the pigment that makes wetsuits black — accounts for 15 to 20% of the rubber foam. Traditionally made from petroleum, it's now increasingly sourced from recycled car tires (ECO Carbon Black). Patagonia has gone further with BolderBlack: old Yulex wetsuits are broken down at the molecular level, and the recovered carbon black goes into new suits. It's the first real wetsuit-to-wetsuit circular program.

Production and labour

SHEICO produces about 65% of all wetsuits globally. Most production happens in Southeast Asia. Patagonia pioneered Fair Trade certification at SHEICO — other brands can participate by paying a per-suit premium that goes directly to factory workers. It's a real improvement, though still limited in adoption.

The chloroprene used to make neoprene comes largely from Denka in Japan. Until 2025, they also operated a plant in Louisiana, in what's known as Cancer Alley — where the surrounding area had roughly 50 times the national cancer risk average, according to EPA data. That plant suspended production after years of scrutiny and over $100 million in losses. The hidden cost of synthetic rubber production.

What you can actually do

Your biggest impact is not which suit you buy — it's how long you make it last. A suit that survives three seasons is more sustainable than a "green" suit that falls apart in one. Proper care, timely repairs, and buying the right fit in the first place all matter more than the material on the label.

Beyond that: buy natural rubber when your budget allows. Support brands that are transparent about their supply chain. Buy from your local surf shop when possible — shorter supply chains, community investment. And when a suit is truly done, look for take-back programs rather than landfill.

Greenwashing

If a brand calls their suit sustainable without specifics, be skeptical. Look for: what the rubber is actually made of (not just "eco-friendly neoprene"), whether the source is FSC or PEFC certified, what glue is used (water-based or solvent-based), and whether the lining is recycled. If they can't tell you, it's marketing.
