R1 Lite Yulex Full Zip LS Top - Mens

Patagonia reformulated the Yulex® material in the 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, they blend the natural rubber with chlorine-free synthetic rubber to increase ozone- and UV-resistance and meet our rigorous standards for strength and durability.

Offering full-arm warmth, comfort and sun protection, the redesigned, neoprene-free R1® Lite Yulex® Front-Zip Long-Sleeved Top is 1.5mm thick, with a stretchy and fast-drying 100% recycled polyester interior lining; the exterior face fabric is made of durable, water-resistant 88% recycled polyester/12% 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).

A streamlined anatomical design holds close to the body for maximum flex, and other features include a vertical front-zip entry with corrosion-proof Salmi® zipper and a low-profile, fused-edge hem at the waist. For additional strength, seams are triple glued and blindstitched, and are internally spot taped at high-stress areas. Made in a Fair Trade Certified™ facility. Suggested water temperatures: 65–75° F/18–23° C.
