Now made in a Fair Trade Certified™ facility, our 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 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, we 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, comfort and sun protection for long sessions in warmer water, the R1® Lite Yulex™ Front-Zip Long-Sleeved Spring Suit is 2mm throughout, lined with stretchy and fast-drying 100% recycled polyester; the face fabric is an 88% recycled polyester/12% elastane blend. The floating front-zip entry provides excellent flexibility through the chest and shoulders and has a corrosion-proof Salmi® zipper that is fully repairable to extend the suit’s lifespan. For additional strength, seams are triple glued and blindstitched, and are internally spot taped at high-stress areas. Easy-access key loop included. Suggested water temperatures: 65–75° F/18–23° C.
