1.Surface material
As far as possible, the surface material of the sleeping bag should be selected from windproof, waterproof and breathable fabrics. Wind and water protection means warmth, and ventilation means comfort. Literally, the windproof and waterproof function and the breathable function are contradictory, but in practice, the multifunctionalization of the fabric can be achieved through modern technology. The interior of the sleeping bag made of multifunctional fabric can maintain a constant temperature, creating a good sleeping environment for users.
2. Sleeping bag filling material
Chemical fiber cotton
Four-hole cotton, seven-hole cotton, nine-hole cotton, P cotton are common chemical fiber cotton.
Advantages: Traditional cotton products absorb sweat but do not dry quickly, while chemical fiber cotton is water-repellent, so it can keep warm in humid environments.
Disadvantages: Not easy to compress, more cumbersome.
Down
Down material can be divided into two types: duck down and goose down.
Advantages: Whether it is duck down or goose down, its warmth is better than chemical fiber cotton; it is lighter than synthetic cotton, easy to compress, and easy to pack; and it has a longer service life.
Disadvantages: Expensive, this is the only downside of down sleeping bags, but for those who want to spend long hours outdoors, Xiaobian still highly recommends buying down sleeping bags, after all, cost-effectiveness is our primary consideration when buying.
3. Temperature scale
From style to material, Xiaobian has been mentioning “warmth”, which is very abstract. Many donkeys can’t grasp the specific concept. In fact, many sleeping bag brands will mark the “comfort temperature” and “Extreme temperature scale” to illustrate the true warmth of the product in actual use.
