Super insulation specification that can be used up to -15℃! Perfect for camping, sleeping in your car, or as bedding for overnight stays! ■The minimum comfortable temperature is 0℃. When using the product at temperatures below 0℃, we recommend that you wear a jacket and underwear properly even inside the sleeping bag. -15℃ cold resistance is the limit at which the fiber freezes and temporarily ceases to function as an insulator when the temperature difference between inside and outside air traps moisture inside the fiber. It means "temperature". Please be careful when using at outside temperatures below freezing. *Recently, I have noticed some harassing reviews from colleagues in the same industry. (I have consulted with each Amazon department.) If you post a fair review, we will take low ratings seriously and work to improve defective products and insufficient explanations, but it is important to note that order information cannot be obtained from the review posting section. There are some buyers who have used the service, posted malicious reviews anonymously, and have not responded to full refunds (have not contacted us). Posting content that may be considered to be a violation of the Amazon Customer Review Guidelines is a violation of the Amazon Customer Review Guidelines. We will identify the poster through review moderation, consult with each department in Amazon's management department, and take appropriate action.
