The goose ( Duvet , Down) has as its main advantage:
Its low weight/volume ratio
Your heating efficiency.
This type of liner is considered first-rate product, and therefore your price is salty.
Sleeping bags with goose feather lining should be avoided by anyone who is actually vegetarian.
Because of your quality to maintain the internal heat, is the type of liner more popular among users who will face the most extreme climates (mostly snow).
One of the secrets to assess the quality of the feathers of a sleeping bag is knowing about your source.
The birds that live in climates with extreme winter have denser and larger plumes.
The conclusion from this data is that plumes of Northern Europe are of better quality than the geese raised in China for example.
Know the origin of feathers of a sleeping bag is mandatory for every user.
Understand what is “comfort temperature”, “temperature limit” and “extreme temperature”.
When purchasing a sleeping bag, it is necessary to have knowledge of where it will be used, and what will be the average of the temperatures encountered with the product.
Every manufacturer of this product discloses three types of temperature: comfort temperature, extreme temperature and temperature limit.
According to data studied understood that a woman’s ability to withstand cold temperatures lower than that of a man.
Warning to feminists on call: think of the word “woman” here as a person in the mood to endure cold, and the word “man” per person high immunity to the lower temperature.
Comfort temperature -temperature outside that a “woman” will support with comfort, and you won’t feel cold.
Temperature limit (transition temperature) – outdoor temperature lower than a man can stand comfortably. Also known as transition temperature.
Extreme temperature – temperature where the technology employed in the sleeping bag can’t isolate the cold outside and there is a risk to health, including hypothermia.
NEVER, under ANY hypothesis, you must choose a sleeping bag based on the extreme temperature.
The “comfort” temperature ALWAYS must be the factor to be examined by the buyer.
If you insist on using a sleeping bag which the climate that will face is next to that of “extreme temperatures” you will die.
