Materials and construction

Crystal Down

Refinement of the plucked raw downs is done by a family business in Germany with the experience of four generations in dealing with feathering. Here the fluffs are washed with well water, then heated up to kill probable germs, finally sorted until there remains just a small proportion of tiny feathers. The larger they are, the more enormous the bulking power and the space for the isolating air cushion. The measures of a Crystal Down 900+ for example are two centimetres from the core to the outer end, and around four centimetres in diameter.


Soft nylon tissue, transports humidity to the outside within short time. Fast-drying, breathing. Used as inner and outer material.

H-Box construction

The H-box, H-chamber and Box Wall Construction is divided into different chambers with vertical side walls to keep the insulation in place and to avoid cold bridges. This ensures a uniform thickness of insulation all through the sleeping bag.
The filling of 90/10 european goose down reaches the Euro Standard 600+ cuin/US Standard: around 650 cuin.
The mixing ratio of down and feather proportion is stated in weight per cents, a waistcoat with a filling of 100 grams in a "90/10"-mixture contains 90 grams downs and ten grams little feathers (one down weighs approximately two thousand grams).

Still some words about care:
You will be able to enjoy your down sleeping bag the longest if you do not roll it for packing up, but stuff it - with open zipper to let the air escape. The small packing bag is determined for use on the way. At home, you should grant the down relaxation and keep it in the somewhat wider dunnage bag. And do not forget to air it before.
