| Source | Sustainably grown (often FSC) rubber trees |
| Used in | Wetsuits and similar gear |
Yulex is a natural rubber derived from sustainably sourced (often FSC-certified) hevea rubber trees, used as a plant-based alternative to petroleum-based neoprene in wetsuits and other gear. It cuts the carbon footprint and fossil-fuel dependence of traditional neoprene while delivering comparable stretch and insulation, popularized in the outdoor world by Patagonia’s wetsuits.
A renewable rubber
One of several sustainable materials alongside recycled polyester and biobased polyester, often made under bluesign standards.
Frequently asked questions
What is Yulex?
Yulex is a natural rubber made from the sap of sustainably grown rubber trees (often Forest Stewardship Council certified). It's used as an alternative to neoprene, the petroleum-based synthetic rubber traditionally used in wetsuits, offering similar stretch and warmth with a much lower fossil-fuel footprint.
Why is Yulex more sustainable than neoprene?
Conventional neoprene is derived from petroleum or limestone and is energy-intensive to produce. Yulex natural rubber comes from a renewable, responsibly managed plant source, substantially reducing the carbon emissions associated with the rubber, which is why eco-focused brands adopted it for wetsuits.
Does Yulex perform as well as neoprene?
Yes — Yulex natural rubber provides comparable stretch, flexibility, and thermal insulation to neoprene, so wetsuits made with it perform similarly for surfing and watersports. The main advantage is environmental, achieving that performance with a renewable material instead of fossil-derived neoprene.
