Filled with 850-fill responsibly sourced goose down and strategically reinforced with Coreloft™ synthetic in moisture-prone zones, it offers exceptional warmth without bulk. The durable Arato™ 15 shell fabric is wind-resistant and compressible, making it ideal for backcountry use or worn under a shell in frigid conditions. Articulated patterning and an adjustable waist ensure comfort and mobility when the temperatures drop.
