Composition: The deciding factor in a down sleeping bag is the down quality. Primarily this is a matter of the weight ratio of down to small feather mixture, which is expressed in percent. Deuter uses only the high performance filling ratio of 90% down to 10% small feather. Trek Lite-Serie: 80/20. Neosphere-Serie: 90/10. Astro-Serie: 95/5. Fill power / cuin: The measurement in cubic inches per ounce of down shows the quality of the loft and expansion power of the filling. High quality down has a loft volume of 650 cu in (10.6 litres) per 1 ounce (28.3g). A loft of 550 cu in, and higher is good; of 650 - excellent; and 800 is almost impossible. In the end: the higher the volume the better the insulation value. Trek Lite-Serie: 625 cuin. Neosphere-Serie: 675 cuin. Astro-Serie: 800 cuin.
