The Evolve Women 4/3mm is the lowest-impact wetsuit in our range. It’s made with Natural Foam instead of neoprene, using 90% natural rubber and 10% synthetic rubber by polymer content. USDA-certified renewable materials, like sugarcane, oyster shells, and plant oils, form a unique blend that gives the Evolve its signature stretch. A testament to wetsuit evolution, the Evolve is a step toward better alternatives, comes with our usual premium wetsuit features, and feels exactly like a wetsuit should.
