On multi-pitch routes or mountain tours, every gram counts. However, a warm insulation jacket is an essential requirement in mountain terrain, to ensure you're equipped for any emergency. This makes the Men's Broad Peak Light IN Jacket an excellent choice. Filled with 90/10 goose down with a sensational 850 cuin fill power, it is ultra-light, can be slipped on as an outer jacket or worn underneath, and in fine weather rolls up in the left front pocket for space-saving storage. The outer material is water-repellent and withstands light showers and the pockets can be accessed easily even when wearing a backpack or climbing harness.
