Sleeping Bags: Goose Feather or Synthetic?

One of the questions that plague some adventurers who like to “get in trouble” is the type of sleeping bag that they must take–which would be better from the point of view of the work to take care, heating capacity, time to warm up. Thinking of helping the people who will face a cold one out there I put together a little comparison between the sleeping bags of goose feather and synthetic fibres. Compare and see what is best for your case.

According to dorsetbudget, there are different types of goose feather for use in sleeping bags to present greater or lesser heating capacity soon there are sleeping bags of goose feather that present larger or smaller factors.

1. Sleeping Bags Of Goose Feather (Down)

The sleeping bags are usually filled with one or two types of goose or duck feathers, goose feathers are infinitely better on heating issue, but are also more expensive. The feathers used in this type of bag are a particular area of the chest of the geese and the older birds have feathers, larger and with better quality for this use.

Goose feather, actually this is not the time with rod and everything, but rather of the filaments.
But as the heat? The heat provided by the sleeping bag runs through a retention process of hot air between the filaments of feathers-the same is true with some synthetic fibers. The difference between the synthetic and the pain of tired lies in the fact that the penalty has a greater holding capacity, mainly high quality pens.

The bags have a percentage of mixture of feathers, which must always be higher in quantity and lower in amount of other. The ideal percentage of this mix is in 90/10, that is, 90% and 10% for other children. Other percentages as 70/30 or 50/50 represent bags with less heating capacity and lower cost.

Advantages Compared With Synthetics
Best weight heating, better compression, better transport body moisture out of the bag (evaporation), heats faster and better than synthetics as long as it’s well taken care of.

Disadvantages Of Compared With Synthetics
Does not heat up well when wet, requires more care, absorbs moisture generated by the body and takes too long to dry if you get wet.

When you choose the goose feather?
If you need light weight and volume and a higher heating factor goose feather is your right choice, environments such as high mountain, where the air humidity is low.

An important tip for those who will use a goose feather bag in some extreme cold environment: keep your sleeping bag inside a watertight bag whenever possible! Avoid leaving the bag comes in contact with the wet point humidity a large area or you will have problems to keep warm!

In Brazil the Deuter sells some models of goose feather, on Trek Lite and Neosphere

2. Sleeping Bags Of Synthetic Fibres

Is the bag type ideal for damp places, with rates higher air humidity, i.e. the bag type ideal for use in Brazil – in fact this type represents the vast majority of existing bags in stores. They are cheaper to buy and easier to maintain. How to dry faster than goose feathers can be washed with a little more ease.

Advantages compared with the sentence
Holds 70% of the heating capacity that is still wet, easier to handle, easier to dry and hardly absorbs moisture generated by the body.

Disadvantages of compared with the sentence
Heavier and lower compression ratio than the goose feathers, does not evaporate moisture from the body with the same ease that the goose, shelf life shorter than the goose down and takes longer to warm up.

When choosing the synthetic fibers?
When the weather is warm and with a greater air humidity the choice is always by synthetic fibers.

Some Tips Regarding Sleeping Bags

  1. A good sleeping bag asks also a good thermal insulator and a good protection against the wind. The loss of heat by contact with the ground or with the wind reduce the thermal efficiency of the environment generated by the sleeping bag, so don’t neglect tent and a good insulator. In case of not simply throw away the insulation and bivouac shelter against the wind by using vegetation, rocks or even riding small “walls” of stacked stones.
  2. No use having a sleeping bag good for cold areas and want to sleep in shorts there. In many cases you can get to sleep even with waterproof clothing. The normal is to use a second skin and fleeces in cold locations here in the country, already in the high mountain environment is common use including the goose feather jackets. But it all depends on the place, remember the concept of layers of clothes and fit in each situation combining clothes and sleeping bag. I usually wear a lighter sleeping bag and sleep with a second skin and fleece and in cold cases I put up the anorak (in Brazil).
  3. Protect your head! This is one of the golden rules on altitude or in very cold places.Bedtime is no different, use wool or fleece Beanies in moderate or cold sites appeal to the hats and hoods of anoraks/high mountain jackets in places of greater cold.
  4. Eat and hydrate properly! Yes, one of the functions of food is to contribute to the heating of the body, so don’t dismiss that hot meal some time before bed.
  5. No alcohol in the cold! The alcohol warms up temporarily but then he contributes to adwindling of body temperature, so in mountain environment no alcohol!
  6. It ain’t no use to have a good sleeping bag if it is wet! Transport your sleeping bag inside a watertight bag, keeping dry is important during the night or even during the day in colder environments.
