Patagonia developed the Tough Puff men's hoody for cold-weather fishing, but gave this insulator jacket enough warmth, style and functionality to deliver on other cold-weather adventures. It's padded with Patagonia's ultralight FullRange® 100% polyester stretch insulation, which offers continous warmth and provides the flexibility to swing flies at the river all-day. It has a durable face fabric, which is stretchy, abrasion resistant and naturally moisture-repellent, and is also coated with a DWR finish to withstand light precip. A smooth and soft recycled polyester Capilene® lining rounds out this technical hoody, delivering moisture-wicking performance. Patagonia furnished the Tough Puff hoody with features like sizeable vertical fly-box chest pockets for handy storage and constructed the sleeve cuffs with simple elastic openings.
