Outdoor Research Women's Size Chart The Illuminate Down Jacket is the lightest, warmest, easiest-to-grab midlayer piece that packs 800-fill responsibly sourced down insulation into its own left-hand pocket. A sturdy nylon shell and lining provide light weather resistance and next-to-skin ultra-soft comfort, while fine-tuned details like a brushed tricot interior and zip chest media pocket ensure hands and valuables stay warm, dry, and safe. Elastic cuffs and drawcord hem trap in warmth and seal out cold, and a color-blocked design looks as good as it performs in freezing temps.
