Product Description

The Fever Zero is the ultimate choice when you need a super lightweight sleeping bag guaranteed to keep you warm. It has a weight of a mere 350 grams and an extreme temperature down to minus 1 Celsius. Weight is kept to a minimum by using a stitched through construction and a half length zipper while insulation is kept at it highest by using the finest quality European goose down available. The bag is a hit for participants in the worlds hardest ultra endurance events like the Marathon Des Sables where you have to carry your own gear. The soft and down proof outer fabric makes the Fever Zero extremely soft and comfortable.

Crystal Down
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.

Next to Nothing
The secret of the extremely low weight lies in the ultra-thin yarn, the diameter of which is only a fraction of that of a human hair. A normal Yeti jacket requires more than 1,000 kilometres of it. Nevertheless, the fabric is both durable and tear-resistant, as well as light and airy. While the original fabric was a mixture of 7d and 10d yarns, the next generation is made exclusively of 7d yarns. This leads to a further weight reduction of 20 %. The total weight per square meter is now only 20 grams - as much as a quarter page of a normal 80 gram printing paper.
