Fibres
Fibre filling is a synthetic product made from polyester and it is very popular because of its high level of insulation, its durability, because it dries fast and it only requires a minimum of maintenance. Actually, today most sleeping bags are made with fibre filling.
The Nordisk Norguard S-PO Eco filling is made from 100 % recycled polyester.
Fibre filling ensures a sleeping bag with a pleasant and soft feel combined with high elasticity and a very good heat insulation. Fibre filling is additionally highly durable even over long term and it requires only a minimum of maintenance.
Compared to down, a synthetic sleeping bag requires less care in cleaning and storage – and it also performs better when wet. Furthermore, since synthetic filling is less costly than down, a fibre bag offers good value for less money.

Down
As opposed to fibre filling, down is a natural material and is by definition a more sustainable choice. Nordisk only uses 100 % traceable european white goose down, giving you the highest possible quality and a guarantee that no animals suffer to provide you with insulation. Please refer to our Ethical Down Code.
In addition to the responsibility factor, down bags are extremely soft and have a unique weight to temperature ratio. With down, you get a ridiculously small pack size and an extremely low weight. The down bag is, however, more vulnerable to moisture and getting wet, which requires a stricter discipline when handling the bag.
Down breathes better than any other material. Furthermore, down and small feathers absorb the moisture emitted by the body much better than most other materials, offering you a soft, dry sleeping experience
Down is NOT the same as feathers, as down grows under the outer layer of the feathers on geese and duck, and have filaments that link to other down plumules creating air pockets. It is these air pockets – and not the down itself – which provide the fantastic insulation.
The general rule of thumb is that the fewer feathers, the better, which is measured as a percentage where 90/10 means that the mix includes at least 90% down and 10% feathers and other particles.
Nordisk only uses high quality European down, Crystal Down, with a special treatment to make them quicker drying as well as preventing odour and mould on the down.
Nordisk down are RDS certified, to secure animal welfare and additionally measured and labelled by EN standards and complies with the EDFA Down Codex and traceability (European Down & Feather Association), which is the only standard which also includes monitoring of actual down standard. The EDFA Down Codex is monitored and controlled by third party (IDFL – International Down & Feather Laboratories).
