We worked hard to create a functional down jacket that provides loft and warmth through the core while eliminating excess bulk where you don’t need it. Our Trudy Jacket's insulation is a hybrid of water-repellent 600 Fill Power DownTek™ down with 100% post-consumer recycled FireLine™ Eco insulation. When durability and moisture management is important, you’ll have the mobility to get after it with reliable warmth for the best winter days and worst cold weather nights.
