DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sleeping bag, and more particularly to improving the moisture absorption and heat retention of the lower leg and the back, keeping the environment inside the sleeping bag comfortable, and the skin temperature of the lower leg. The present invention relates to a sleeping bag that promotes a decrease in body temperature by increasing the degree of increase in body temperature and facilitates sleep.

[0002]

2. Description of the Related Art Heretofore, sleeping bags which mainly use a batting made of cotton, feather, polyester hollow fiber, or the like having a heat insulating property between a top sheet and a back sheet have been mainly used.

[0003]

However, these conventionally known sleeping bags have the following problems. In other words, when cotton is used for batting, although it has water absorption, it needs to be sufficiently dried after use, and in order to enhance heat retention, the amount of batting used increases and the weight increases. Disadvantages, and it is rarely used recently. In addition, sleeping bags using feathers as batting are also known, and are good in terms of heat retention and weight reduction, but in terms of price, they are expensive and use feathers that are natural materials. Careful care, such as sufficient drying, was required. Therefore, recently, as a batting for a sleeping bag, a sleeping bag using a batting made of polyester fiber, polyester hollow fiber, or the like has been widely used. However, batting made of these polyester fibers and polyester hollow fibers, etc., has almost no hygroscopicity,
The humidity inside the sleeping bag was increased, the inside of the batting was filled with moisture, and dew condensation occurred inside the top sheet and the back sheet of the sleeping bag, and the sleeping bag had a disadvantage of stickiness and reduced heat retention. Therefore, the insulation is high, the environment inside the sleeping bag is comfortable,
It has been desired to supply a sleeping bag that does not require much work after use.

[0004]
