Here is the parka that will keep you smiling in the face of cold weather. A unique 3-layer design provides the warmth of most baffled parkas, but with less weight and fewer exposed seams on the outer shell. It is cut longer throughout the body and capped with an outer shell made from Gore Windstopper™ for an ideal balance of water resistance, warmth retention, and breathability. At just 25 oz (710g), our Ion is one of the lightest big mountain parkas you will find.
