Our First Ascent guide team built this ultralight jacket for alpine climbing in cool to cold weather. Windproof ripstop polyester shell. Each cluster of the super high-loft 800 fill StormDown insulation is also treated with a DWR finish so the down retains its loft and superior insulating properties even in wet conditions.
