The final ascent was strenuous, steep and serious. An icy wind is blowing at the summit, threatening to strip your core body heat in seconds. Time to pull on a lightweight, high-performance insulation layer – no matter what season it is. Down has an excellent warmth-to-weight ratio. This makes it ideal for mountaineering insulation jackets and sleeping bags. You produce the heat, down traps it as warm air and holds it next to your body. It also packs down super small in your pack. SALEWA® only uses Responsible Down Standard (RDS) certified down. What does that mean? The standard guarantees that our down and feathers only come from ducks and geese that are well treated with high animal welfare standards. For more information about the RDS standard, visit
