FJÄLLRÄVEN DOWN
Never feel cold again
When it comes to functional materials, nature usually knows best. And down is no exception. It keeps birds warm in all kinds of cold, from the extreme to the mild. And it does so without adding bulk or weight.
Our down journey started in 1974 when Fjällräven founder, Åke Nordin, promised to make a jacket that provided welcoming warmth through the coldest of Swedish winters. The jacket was the Expedition Down Jacket and it was filled with 600 CUIN of quality down.
The Fjällräven Down Promise is now recognised as one of the best in the outdoor industry. Find out more here.

HOW DOES DOWN WORK?
When you look at a down feather under a microscope it looks like a tree. The stem, the part that attaches to the bird’s skin, is the trunk. Lots of small fibres branch out from the stem into ever-smaller fibrils. This loose structure traps air in the spaces between the fibres and it’s this air that insulates against heat loss.
The mix of regular feathers to down and the fill-power (CUIN) affect the ability to trap air and in turn the warming power of the jacket. As a rule, the more down to feathers and the higher the CUIN number, the warmer the jacket.
