Synthetic or Natural Down Sleeping Bags

Choosing a sleeping bag:

Natural or synthetic down, which to choose?

To purchase a sleeping bag it will first ask the following questions about its use:
Where? when? by what temperature? in what conditions ? at what frequencies? what budget?

We will not address the same way when choosing a sleeping bag that will be used to camping in summer, as the one used to sleep in the mountains under the stars …
You will find 3 indicative temperatures on your bag sleeping:
-The t ° comfort: as its name suggests, this range of t ° you a good night
-The t ° comfort limit: from it, you will feel an impression of cold
-The t ° extreme: from which your life may be in danger

You will hear often that natural down will be most suited to very cold temperatures, though I’m not entirely agree because it also has real drawbacks:
-the natural down is very difficult to maintain (washing, drying etc.)
-once wet it will be long to dry, and this is really problematic
-it resents compression
-it is very expensive

Nowadays, some manufacturer offer sleeping bags synthetic material that can be used in t ° cold, which give a very satisfactory result (the north face, WILSA for example), with a much more affordable (about 150 euros) against about 450 for natural down.
Be sure to choose a bag for your morphology, too wide a bag evil retain heat, it is also important to emphasize that it is not useful to multiply the layers of clothing inside the bag because you will lose also the insulating effect of the air.

Importantly, the congestion in the backpack: today you will find bags “ultralight” whose performance is good but not exceeding 1kg, again it all depends on the use you make of it.
You can also pair your sleeping bag outer bag to a gore-tex which will isolate you very well to soil moisture, but it will be useless for nights in tents or shelters.

Finally, the number of models on the market this will allow you to find your perfect happiness provided you follow these tips, and choose wisely.
