Spyder is amazed at the intense cold weather that attacks the mountains every year, so it made the Men's Bernese Down Jacket to face the icy conditions head-on. The durable shell crafted from Pertex Shield with a Spylon+ DWR treatment not only resists moisture, but it also retains its strength after each use while resisting abrasion. The baffled construction is insulated with incredible 700-fill Power Down, which is surprisingly lightweight and packable into the included stuff sack. This high-performance design is extremely helpful on base camp excursions and freezing morning hikes in the canyon. The Bernese Down Jacket not is not only equipped for subzero outdoor adventures, but it?s also ready to handle warm day trips. The convenient underarm vents help create necessary airflow while the adjustable cuffs give you a personalized fit. This jacket also features a draw cord at the hood for secure coverage, as well as a chest zip pocket and two side zip pockets to store your energy bars as you summit.
