The best warmth to weight jacket Patagonia has ever created, the Women's Micro Puff Insulated Jacket perfectly blends a super-lightweight shell with soft, compressible PlumaFill insulation to make it both an ideal insulating layer and a cozy outer layer. Windproof and water-resistant, the lightweight Pertex Quantum shell keeps you protected from the elements as you make your way down the mountain, while PlumaFill insulation maintains its heat-trapping loft, even after getting wet and abused through seasons of use. Its innovative quilting construction complements the insulation by stabilizing and maximizing the loft of the down-like PlumaFill strands with minimal stitching, and the center-front zipper has a wicking interior storm flap and zipper garage at the chin for baby-soft comfort and minimal chafing. Add on the stowaway left hand pocket, and this jacket is guaranteed to be your go-to for ambitious outdoor excursions and routine trips around town alike.
