The best warmth for weight of any jacket we’ve ever built, the Micro Puff® Jacket delivers ultralightweight, water-resistant, down-like warmth with PlumaFill synthetic insulation—a revolutionary featherlight down alternative.

It’s like down, only better—Patagonia's Micro Puff® Jacket uses a revolutionary, feather-soft synthetic insulation with an unprecedented warmth-to-weight ratio. The groundbreaking PlumaFill insulation (65-g 100% polyester) is phenomenally light and compressible, offering down-level warmth that still traps your heat when it’s wet. A nylon ripstop Pertex Quantum® shell, with a DWR (durable waterproof repellent) finish, blocks wind and snow. The garment’s design maximizes performance and minimizes useless fluff. Features: zippered handwarmer pockets (the left pocket doubles as a stuffsack with a reinforced carabiner clip-in loop), a pair of sleek internal drop-in pockets (made without excess, using the backside of the handwarmer pocket bags), and elasticized cuffs and hem.

Water Resistent

DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.
