The Patagonia Women's R1 Yulex 3/2.5 Back Zip Wetsuit is now made in a Fair Trade Certified facility. These neoprene-free Yulex wetsuits are made of 85% natural rubber/15% synthetic rubber by polymer content. Replacing a petroleum-based material with a plant-based one, they offer the same warmth and performance attributes as conventional stretch neoprene while reducing CO2 emissions by up to ~80% in the manufacturing process. Derived from sources that are Forest Stewardship Council certified by the Rainforest Alliance, natural rubber has been blended with chlorine-free synthetic rubber to increase ozone- and UV-resistance, and meets rigorous standards for strength, stretch and durability. With new patterning for maximum flexibility and improved fit, the R1 Yulex Back-Zip Full Suit is 3mm in the torso and thighs, lined with high-stretch, fast-drying 95% polyester (51% recycled)/5% spandex inverted microgrid; 2.5mm in the arms and legs, lined with high-stretch, fast-drying 100% recycled polyester jersey; the face fabric is 85% recycled polyester/15% spandex. The face fabric and lining are now solution dyed—using 86% less water than conventional dyeing—and are laminated with water-based AquaA glue that’s free from harmful volatile organic compounds (VOCs). The suit’s center-back zip allows easy access and has an internal gasket to prevent water entry. Supratex kneepads and ankle cuffs provide excellent abrasion resistance and increased durability. 100% external seam sealing; all seams are triple glued and internally taped. Easy-access key loop included. Suggested water temperatures: 60–65° F/16–18° C.
