For winter hiking trips or urban adventures , this water-resistant Columbia Men\'s Lake 22 Hybrid Down Jacket mixes down insulation and stretch fabric. The HEAT SEAL construction prevents any cold spots thanks to thermal bonding which is used to seal in each baffle of insulation so you can make the most of the 650-fill power down insulation to stay warm. The arms are made from stretch fabric so you can move easily. For added protection from the cold and an optimal fit, it has a chin guard and binding on the hem, collar and cuffs. Safe storage for your essentials is provided thanks to the zippered hand pockets.
