If you mean water shedding performance in fishing apparel, the strongest matches are the jackets and layers built to repel spray and rain while staying fishable. The Aftco Mariner Jacket is a lightweight waterproof option with DWR and a breathable membrane for wet, windy days. The Frogg Toggs FTX Elite Jacket is the most weather-protective pick here for all-day rain. The Aftco Tactical Bassin Shadow Performance Fleece adds light moisture shedding for cool conditions, while the Simms Fishing Men's Confluence Shirt is a performance shirt that sheds water and works well for active casting. For hands, the FishMonkey Fish Monkey The Blocker Neoprene Fishing Glove helps keep water off while preserving dexterity.
Switch to heavier waterproof outerwear when you expect steady rain, cold wind, or long runs in open water. Switch to a lighter performance shirt or fleece when conditions are just spray, mist, or brief showers. If you meant water shedding on fly-tying materials, then EP Flies EP® Fibers or EP Flies EP® Fibers 3-D are the better fit.
