The Patagonia Long-Sleeve Rugby Shirt is built from Regenerative Organic Certified cotton jersey, a standard that goes beyond organic to support farming practices that rebuild soil health. The woven collar and rib-knit cuffs give it the structure of a classic rugby shirt, so it reads as put-together at the trailhead or around a campfire without trying too hard. What Our Gearhead(R) Experts Are Saying:"The woven twill collar holds its shape wash after wash, and the rib-knit cuffs keep the sleeves from riding up when layered under a fleece at camp."
