Synthetic vs Down Sleeping Bag Review

The different materials meet.

Synthetics: Different kinds of synthetic exist regardless of how manufacturers call them, synthetic fiber can be full or channels. The thickness, quality and the amount of fiber present in per square meter will have a bag hot or very hot. Low range bags for warm weather often consist of full fibre to 200 g per square meter, the highest range bags will be filled with hollow fiber to 400 gr M². Hollow fiber or channel (a bit like a macaroni) offers the advantage of better contain the heat. The channels (from 1 to 4 according to manufacturers) contain air that is an excellent insulator. You can also meet some forms of synthetic as the Loft Micro which is other than one approaches a synthetic sleeping bag. Benefits in addition to a very attractive price compared to the performance of the bag will be in easy maintenance. Another advantage, the synthetic does not fear the moisture, it can stay warm even if it is wet and it will dry quickly. The disadvantage of these bags is that to have good performance we find ourselves quickly with a bag a bit heavier and bulky, its compressibility rate / loft is also lower than the down but with the latest research we will raproche more and more with these fibers of a quality comparable to the pen.

Down: We find on the market of the sleeping bags down at all costs, the most expensive to the cheapest! It’s the overall quality of the snowflake which is the cause, more down is thin and flaky, greater swelling, warm, lightweight and compressible. In addition, it is natural (what else?).The French down will also superior to Asia down… the reason is simple… the French poultry are not high in battery and their down grows much better as flannel sleeping bags on the Internet! (Check http://www.pimasleepingbags.com/best/flannel-sleeping-bag/).

The best Snowflake is reflected in the high range for mountain sleeping bags. Valandré and society Transplume are the pioneers. This down is achieved by pulling to keen on white geese of the Pyrenees. The volume by oie is not huge: 20 to 30 grams and the amount required for the manufacturing of a bag of high-altitude sometimes exceeds the kilo, which corresponds to + – 50 geese or ducks 80 (between fatty liver and culture of fluff, it’s not good to be a poultry in the Pyrenees). Understand that the bags employing bright down are often very expensive and rare.More France pulling raw became prohibited. (Composition and manufacturing of such a bag require several days of work! For more information see the excellent site of Valandré).

On this example we can analyze for equal weight the force of filling between a down (from left to right), snowflake, 80/20 and a duvet pure Goose (95/5).

More affordable, the classic down, duck or goose. It’s down harvested after the slaughter of young animals. It will be sorted and cleaned before be offered in different dosages between the down itself and the snowflake. This is how we can find names 90/10 or 80/20… It’s the percentage of flakes / feathery. The higher the percentage of down and over the bag will be ready for the feat.
