The Nike ACG Lava Flow Ultralight Therma-FIT ADV women's down jacket, in Bold Berry/Monarch Purple/Monarch Purple/Summit White, is built for trail runs and hikes in the deep cold. Its 1000-fill goose down delivers maximum warmth at around 210 g, while the water-repellent nylon shell stands up to damp conditions. A snug hood, two-way zip and hem bungee let you fine-tune protection, and the jacket packs into its own pocket so you can travel light. Wear it over a base layer or under a waterproof shell; reflective details add visibility.
