Y by Nordisk Passion Three Sleeping Bag L navy

The Passion Three is one step higher in insulation performance in the ultra-light Passion collection from Yeti. This is achieved by using the H-chamber construction, which improves insulation performance by giving the filling more room to collect heat. The filling is the highest quality European goose down on the market and the very soft and down dense fabric makes the Passion Three extremely soft and comfortable. You choose the Passion Three if you want to keep the weight of the down low but need more protection from the cold than its ultra-light little brother, the Passion One.

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.
