Patagonia Men’s Long-Sleeved World Trout Slurped Cotton T-Shirt. Because Patagonia—like their salmonid counterparts—prefer clear, cool streams and rivers, they’re donating five dollars of the full-price sale of the Long-Sleeved World Trout Slurped Cotton T-Shirt to World Trout. Original artwork from A.D. Maddox is screen-printed onto a lightweight, organic cotton T-shirt using PVC- and phthalate-free inks. Fabric has a soft enzyme-washed finish. Taped shoulder seams provide excellent fit retention and comfort under a vest.
