The Summit Jacket is our upgraded version of the classic lightweight down jacket – a performance-minded, go-anywhere outerwear piece. The ripstop outer shell houses Thinsulate synthetic insulation and is treated to offer water repellence in a pinch. Loaded with features like sueded pocket liners, Lycra sleeve binding, and adjustable hem, it is sure to keep you warm and protected. When you need to pack it away, the Summit compresses down into its chest pocket for easy storage.
