What is the difference between down Sleeping bags and cotton Sleeping bags
1. Different filled materials
The fillers of the down sleeping bag are duck down or goose down. Duck down generally contains 85 to 90, and the velvet content of goose down can reach 90 to 95.Generally speaking, the higher the expansion of the down, the better the warmth of the velvet, and the degree of heating at the same condition is slightly higher than the duck down.
The filling of the cotton sleeping bag is chemical fiber cotton. There are many types and different quality.

Among them, seven or nine -holeThere are more chemical fiber cotton products, which is better to keep warm.
2. Different performance
The performance of cotton Sleeping bags is similar. As the use time increases, the warmth performance will slowly reduce until it cannot be used, but one of the advantages that they do not have in a down sleeping bag is that they can remain some warm performance after wetting.Once it is wet, it does not keep warm or even negative.
Compared with two types of fillings of down and chemical fiber cotton, the degree of downness of down is higher, and the weight can be achieved light at the same degree of warmth.Chemical fiber cotton is relatively bottomed, with large packaging volume and poor compression.The down is expensive, cheap chemical fiber cotton, down humidity will lose almost all the warmth, and it is not easy to dry. Therefore, it is often used in the rigorous mountaineering environment to use the material with waterproof and breathable properties as the outer ingredients of the down sleeping bag.After wetting, maintain a certain amount of warmth, and fast drying speed.
3. Different service life
The use of down products is very long. Good maintenance can be used for more than 10 years, while the life of chemical fiber cotton Sleeping bags is only 3 or 4 years.The requirements of down Sleeping bags have high requirements for internal and external materials. The lining materials usually require more than 200t, so the overall life span is longer.

Once a moisture, it will lose warmth.Although the cotton sleeping bag is not good for folding and resistant to resistance, its hygroscopic resistance is better. Even in a humid environment, it can still have a certain amount of warmth and easy to dry. It is suitable for use in areas with more rain.
The cotton sleeping bag is not easy to squeeze. Each squeeze and twisted twisted will cause countless cotton fiber to break or deform. These damaged cotton fibers cannot be fluffy, which means that every time you compress the cotton sleeping bag, it has a warmth ability to keep warmThere will be an irreversible loss of loss.If there are too many damaged fibers, the cotton sleeping bag will collapse.
The down sleeping bag is easy to squeeze. Each velvet is composed of many velvet wires. The down of the down of the protein is good, the pressure is resistant and folded, and the fluffy loss is not large after multiple compression.So as long as it is not a fake down sleeping bag, the service life is much better than the cotton sleeping bag.
