Fill Power: 650 DownTek
The Greystone 20° uses 650-fill DownTek water-repellent down. Some retail listings reference a 600-fill version from earlier production; the current spec is 650-fill. Higher fill power packs lighter and traps more warmth per ounce, so the 650-fill version delivers better loft and compressibility for the same 20° rating.
Warmth and Design
Mummy-style construction with women's-specific sizing and warmth mapping keeps you comfortable to 20°F. The water-resistant coating repels moisture in damp conditions.
Sustainable Materials
Recycled shell and lining fabrics deliver performance with sustainability in mind.
