Patagonia: Men's R1 Lite Yulex Short John
This Patagonia have reformulated the Yulex material in their spring suits, making them lighter, stretchier and more comfortable. Made of 85% natural rubber/15% synthetic rubber by polymer content that replaces 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, the blend of natural rubber and chlorine-free synthetic rubber helps increase ozone- and UV-resistance and meet Patagonia's rigorous standards for strength and durability.
Offering warmth, comfort and sun protection for the core with an open-arm design that offers freedom of motion for long miles in open water, the neoprene-free R1 Lite Yulex Short John is 1.5mm throughout. The interior lining is stretchy and fast-drying 100% recycled polyester; the face fabric is an 88% recycled polyester/12% spandex blend. 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). A corrosion-proof back zipper allows easy on/off; seams are sewn with flatlock construction for next-to-skin comfort. Internal key loop included. Made in a Fair Trade Certified facility. Suggested water temperatures: 18–23° C.
