The Shadow 500 is a near heavyweight down bag that offers first class down protection under the most extreme conditions. The outer fabric is unique for a Yeti bag by being the only of our bags produced in the "LightyAsh" shell that offers a soft and cotton like feel that as a bonus guarantees reduced sliding on your mat. The bag is filled with fine quality European goose down and has a semi mummy shape that makes the bag spacious and comfortable. The Shadow 500 is the choice for any adventure set in extreme conditions where you still have the option to choose that little extra comfort.
Energetically, geese and ducks are the most efficient combined heat and power plants of all time. Thousands and thousands of super-soft filaments, consisting of the horn substance keratin, grow radially from a tiny core. Each of these filaments is provided with innumerable fibre ramifications. If many down come together, they stick together with their hooks and form many small heat-storing air chambers. A natural system that is lighter, more flexible and better insulated than anything man has ever invented. Yeti goose down achieves the highest possible bulking power of up to 900 cubic inches (cubic inches). Yeti exclusively uses European down, mainly from Germany and Poland. Every single down complies with the EDFA Traceability Standard.
