The keys to comfort are versatility and layering. Fortunately, the 3-in-1 River Salt Jacket provides both. The outer shell is made from a tough H2No® Performance Standard 4-layer polyester microfiber with a waterproof/breathable barrier and a DWR (durable water repellent) finish—the same fabric we use in our toughest waders. Three TPU-coated, water-repellent front-zip pockets hold fly boxes, while the corrosion-resistant YKK® Vislon® Aquaguard® main zipper holds back the weather. The vented, fully adjustable hood stays in place even at high boat speeds. Inside, a light, warm and durable Nano Puff® Hoody (insulated with 60g PrimaLoft® Gold Insulation Eco) keeps you warm to the top of your noggin and snaps out to be worn alone when the deluge lets up. Put it all together and you have a fly fishing jacket that helps you keep up with weather conditions—no matter how fast they change.
