JUYEE Sleeping Down Sleeping Winter Minimum Temperature Premium Down Mummy Sleeping in the Disaster Prevention and Evacuation Bag, Bag, -10℃, 650FP,

[Sluff filled with high quality down 650FP] When used, the down expands with air, providing both warmth and comfort, allowing you to sleep comfortably and comfortably in cold environments. In addition, when stored, the air from the down escapes, allowing for lightweight and compact storage. [Construction that will keep you warm until morning] The side zipper is a 2-way type that can be opened and closed from the top and bottom, preventing the fabric from getting caught. The draft tube that blocks cold air from entering through the gaps in the zipper and prevents warm air from escaping, and the shoulder warmers around the shoulders further enhance heat retention, and the box-shaped feet are roomy so you won't feel cramped. [Mummy-shaped sleeping bag that fits the human body shape] Mummy-shaped sleeping bags are characterized by higher heat retention than envelope-shaped bags, as they closely fit to the body and have fewer unnecessary gaps, making it difficult for body heat to escape. Mummy-shaped sleeping bags are also lighter than envelope-shaped sleeping bags, and can be folded compactly for storage. [Uses ultra-fine nylon fibers] This is a high-grade fabric that is water repellent and has both strength and softness. By using a nylon fabric with good heat retention on the inside, it is breathable and soft to the touch, so you can feel warmth as soon as you enter the sleeping bag, allowing you to sleep soundly and comfortably until the morning. [Various uses depending on the situation] You can enjoy outdoor activities such as mountain climbing and camping warmly even in autumn and winter. Even if you don't usually go camping, we recommend it as one of your disaster prevention items. It's great for mountain climbing, camping, sleeping in your car, staying in the lab, staying at a friend's house, or when evacuating during a natural disaster.
