Windtour Envelope Lightweight Portable Sleeping Bag

Keeping the sleeping bag dry is important to improve the quality of sleep in the sleeping bag. The water absorbed by the sleeping bag is not mainly from the outside world, but the human body. Even in extremely cold conditions, the human body will still discharge at least a small cup of water during sleep. After being damp, the thermal insulation cotton will stick and lose its elasticity, and the thermal insulation ability will decrease. If the sleeping bag is used continuously for many days, it can be dried in the sun. Frequent cleaning of sleeping bags can be used to keep the thermal insulation cotton elastic.

Of course, wearing more clothes during sleep can also achieve satisfactory results. These clothes need softer clothes, and they can also be used as thicker pajamas. Filling the gap between the person and the sleeping bag can also enhance the warmth retention of the sleeping bag.

The human body is the source of heat for the sleeping bag. If you do a short warm-up exercise or drink a cup of hot drink before going to bed, your body temperature will increase slightly and help shorten the warming time of the sleeping bag.
