The Micro Puff® Hoody delivers the best warmth-to-weight ratio of any jacket we've ever created. This unprecedented combination of warmth, minimal weight, and compressibility-even when wet-offers the versatility of synthetic without compromising the benefits and feel of down. The revolutionary PlumaFill insulation (65-g 100% polyester) is featherlight and compressible, offering the down-level warmth that still traps your heat when it's wet. A nylon ripstop Pertex Quantum® shell, with a DWR (durable water repellent) finish, blocks wind and snow. The garment's design maximizes performance and minimizes useless fluff.
