On pre-runoff floats, the fish are hungry, the waters clear and conditions change faster than you can refresh your forecast app. The keys to comfort are versatility and layering. Fortunately, our 3-in1 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 wader line. 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 60-g PrimaLoft Gold 100% polyester) 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.
