Patagonia's 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, they blend the natural rubber with chlorine-free synthetic rubber to increase ozone- and UV-resistance and meet our rigorous standards for strength, stretch and durability. Offering full-arm warmth and sun protection in a streamlined, formfitting design, the R1® Lite Yulex Long-Sleeved Spring Jane is 2mm throughout, lined with stretchy and fast-drying 100% recycled polyester; the face fabric is an 88% recycled polyester/12% spandex blend. The vertical front-zip entry allows easy on/off; seams are sewn with flatlock construction for next-to-skin comfort. Easy-access key loop included. Suggested water temperatures: 65–75° F/18–23° C.
