Looking for a truly high-performance, technical, insulated vest? You found it. The Fusion 90 Vest is built from the same materials as our angler-favorite 3/2 Puffy Jacket. 90 grams of synthetic, spiral bound synthetic insulation trap heat, while an abrasion resistant, water repellent, 4-way stretch shell locks wind and weather out. An adjustable, insulated hood keeps your head and neck toasty. The Fusion 90 Vest is perfect for variable weather days when you want multiple layering options. Wear it as an outer layer for mild conditions or a core-furnace midlayer if the temperature turns bitter.
