Comfort DOWN
COMFORT DOWN has a quality down with a fill power of 550+. With the traveller in mind the Comfort bags are designed to give maximum comfort to the user. When travelling in differing temperatures the roomy shape and the “easy-access”. The two zipper system allows you to adjust the warmth according to the local temperature and make travelling more comfortable; one zipper in each side allows you to open the bag totally, this gives easier access to the bag. You can also sit in the bag with full freedom of movement for arms and legs.
80/20 down with Fillpower of 550+ (EU) gives performance, soft feel and excellent durability. The mix of down and feathers are optimized for the best performance and compressibility and with comfort in mind.
This construction uses less material and is the obvious choice for lightweight bags. As the walls are slanted it is always insulation behind the wall, and no cold spots.
Some information that will assist you with researching or buying a down sleeping bag to suit your needs.
The quality of down is measured using two criteria: its Fill Power and Down Content.
The Fill Power of down measures the strength of the down, or its ability to resist compression, and how well it can loft. A Fill Power rating of 600 indicates that a 30g sample of down will occupy 600 cubic inches when subjected to a standard compression force. The higher the Fill Power the better the down. Down do not all perform equally. Bags with down of a higher fill power give more loft and warmth for the same weight.
The US system of measuring Fill Power differs from the European system so, when comparing qualities you need to take into consideration that the US system will appear to give a better Fill Power, for example:560+(EU) = 610+(US), 660+(EU) = 725+(US) and 750+(EU) = 850+(US). Nanok uses the European system.
Down is graded according to the mix of pure down clusters and small feathers. This is represented as a percentage ratio, for example: 80/20, 90/10. Down which is quoted as being 80/20 indicates that it comprises 80% down cluster and 20% small feather.
The construction utilised in a down sleeping bag is as important as the down filling itself. Optimal sizing an construction of channels and down fill is paramount to avoid cold spots and low thermal efficiency.

Down constructions
Box wall construction is the most efficient construction as the down is held in place using “walls” of material dividing the channels. These walls are not straight to avoid cold spots.

2 layers for maximum insulation. 2 layers of down with opposite walls. Mainly used in extreme winter bags.
A trapezoid construction keeps the down in place nicely, and prevents cold air to get through the seams.
