Rectangular/Mummy-type Hybrid Sleeping Bag That Withstands Extreme Cold

About the Product

The most important factor in withstanding extreme cold is the plenty of padding. The model with 1800g of padding weight is designed for temperatures down to -25℃, and the model with 1500g of padding weight is designed for temperatures down to -15℃. (This has not been tested by a testing institution. Please note that this is our own standard for the amount of cotton. Please note that this is not a recommendation for use in this temperature range, as it may cause health problems in some cases). In addition, the sleeping bag is equipped with a cover to prevent cold air from the zipper, and a peach skin fabric is used for the inner fabric to keep you warm from the moment you enter the sleeping bag. It prevents the coldness that is easily felt with ordinary polyester material. The outer fabric is made of 240 taffeta, which is impervious to rain and wind, to keep the warmth inside.

For the filling, we use "Microprima," an artificial down that reproduces the fiber structure of feathers with man-made ultra-fine hair to achieve warmth, softness, and lightness. The high fiber density creates a layer of air inside the sleeping bag, keeping warmth in without losing warmth. Since no animal materials are used, there is no odor, and it is machine washable, so it can be kept clean at all times. In addition, artificial down does not impose sacrifices on waterfowl and other animals, which we believe contributes to animal welfare.

Other features for ease of use. The zipper has a guard to prevent hair from getting caught in it or the zipper from opening by itself while sleeping. In addition, the double zipper can be opened and closed from both the outside and the inside, so it can be opened and closed smoothly when sleeping. To further facilitate storage, the structure of the case has been designed to make it easy for even the weakest users to put it away. The included belt can be used for more compact storage.
