The Women's Arc'teryx Patera Parka is warm and weatherproof for pushing through the coldest winters in the city. The parka length and a spacious hood offer ample coverage from head to knee. The Down Composite Mapping utilizes 750 fill power down and Coreloft synthetic insulation in high-moisture areas to provide high warmth with low weight. The durable GORE-TEX shell is waterproof and windproof, preventing snow, sleet, and wind from seeping through.
