A high-performance, neoprene-free wetsuit made of 85% Yulex® natural rubber/15% synthetic rubber by polymer content with a recycled nylon lining; the natural rubber is from sources that are Forest Stewardship Council® certified by the Rainforest Alliance. Suggested water temperatures: 60°–65° F/16°–18° C. Made in a Fair Trade Certified™ factory. I only used it once, and then I lost a bunch of weight, so it no longer fits. Best wetsuits made. I replaced it with the same model.
