Flylite

The FlyLite from Western Mountaineering is a down sleeping bag optimized for weight. However, the sleeping bag not only weighs a minimal 395 grams, it also has a minimal packing size the size of a water bottle. The mummy sleeping bag is made of light and down-proof polyamide on the outside and inside, which is impregnated perfluorocarbon (PFC)-free. The down sleeping bag warms with 850 goose down and a few feathers. The filling is located in circumferential down chambers so that you can actively move them to the side where you need more filling. The hood is extra thickly lined and there are no cold bridges as there are no seams sewn through. The interior material is dark so that the sleeping bag dries faster in the morning.
