yeti, the Daunenschmiede from Görlitz, sends with the new Fever Zero Sleeping bag a lightweight among the summer sleeping bags in the race. We took a closer look at the down sleeping bag and tested it.
Materials and manufacturing
With a weight of only 280g and minimal pack size, the Fever fits in even the smallest daypack. Many sleeping bags and pretty much every mattress should be heavier! This low weight can only be reached with a high-quality down filling and a special, lightweight fabric.
The Next to Nothing 2.0 technology describes a special microfine nylon fabric that weighs only 25 grams per square meter, making the Yeti the world's lightest, downproof material from Toray in Japan. The material is water-repellent and still breathable so good climate is taken care of.
This Stöfflein covers 110g Yetis high quality Crystal Down, The Fever is made up of a mixture of 95% down and 5% support feathers with a bulk strength of 900cuin. The fact that the down comes, as in the case of the fever, from the welfare of European farms, is unfortunately not always self-evident. For tracking "from the egg to the sleeping bag" the Yeti Ethical Code was developed. Thus Yeti guarantees the traceability of down production.
In practice
The Fever is really "a handful of sleeping bags". The pack size and weight impressed already. I have it combined with the light weight Exped sleeping pad and one Biwaksack tested at about 12 ° C on the shores of Lake Constance and slept pretty well. The rest of the condensation, the sleeping bag well put away, shake a few times and after the coffee, he was dry again.
The only about hip-length zipper in my opinion could be a bit longer, so you can spread the sleeping bag further.
Conclusion
A proud price with around 400 ¬, but which has its justification: the Yeti Fever Zero is in its temperature range probably the lightest sleeping bag on the market. In addition, it is produced qualitatively flawlessly and also in front from an ethical and ecological point of view: controlled down from species-appropriate goose breeding in Poland, manufactured in Germany. Yeti is so sure of its quality that with its 5-year warranty, you get a 3-year warranty.
