The Marmot Helium sleeping bag packs smaller than a loaf of bread, weighs less than a kilo and keeps you warm down to -10 Deg C, making it ideal for lightweight mountaineering and backpacking. The down used is of the highest quality and this lofts extremely well for maximum heat retention and warmth. The Marmot MemBrain technologies keep the weather out with a 20,000mm in waterproof performance and have 20,000gr in breathability to keep your sweat out of the sleeping bag, again to keep you warm and your sleeping bag dry, because of this technology a liner or any other 3 layer constuction is not needed so keeping pack size down.
