Duck feathers 750 g (down/small feathers – 90/10, fill power – 700 cuin)

These days, duck down ranks among the highest-quality natural filling materials. Its strengths are superior thermal insulation properties, very low weight, and good compressibility of the filling – ensuring a small volume. All that while maintaining a long life. Thanks to these strengths it meets the high requirements that are placed especially on winter expedition sleeping bags.
In down sleeping bags, down is mixed with small feathers. Down fulfils the insulation function, while small feathers provide the “loft” effect – fluffiness. With down you also get a unit called the ‘cuin’ (cubic inches), which shows the down’s maximum ability to fill up volume. The higher the value, the better the fill power.

Very soft, light, and breathable 100% nylon fibres that are also sufficiently strong and elastic. That’s why they are very resistant to tearing or other mechanical damage. This material is water-repellent and also suitable for low temperatures, since it has good thermal insulation properties.
