Crystal Down®
We develop equipment for expeditions exploring the coldest areas of the world and therefore, all our products are filled with Crystal Down® – a selection of voluminous European down. A single Crystal Down® has a diameter of up to 4 cm and white fluffy "arms" to entrap air and support insulation. It takes up to 1000 pieces of Crystal Down® to reach just 1 gram of filling.
Down is a lightweight and natural insulation material. Keeping waterbirds warm all winter and still light enough to fly, down are complex structures with thousands and thousands of soft, keratin filaments that grow radially outwards from a tiny centre.
Down insulation keeps you warm and compresses well, leaving you with more space in your pack.
Crystal Down® Dry
Natural down has a tendency to collapse when wet, which occasionally has left down fanatics frustrated (and cold) in humid conditions. But not anymore.
DWR (Durable Water Repellent) technology prevents down from absorbing water, thus eliminating the one disadvantage clinging to nature's insulation material. We refer to this hydrophobic down as Crystal Down Dry®.
We originally introduced this down technology in 2014 and now use Crystal Down Dry® in a wide range of products including the Arctic range of high-end sleeping bags and the entire range of down filled rain jackets, empowering polar adventurers and weekend outdoorers alike to take on any weather conditions.
Down sleeping bags
Each product is marked with a special code that reveals the down quality and the origin of the down. The code is divided into sections that carry different meanings.
As an example, the code 800RP1PWKG955 divides into 800 | RP1 | PWKG | 95/5
* Fill power is also called loft and it is measured by laboratories under the supervision of the International Down and Feather Laboratory (IDFL) in Salt Lake City, USA.
