Cold ? We can use fire or extra layer of clothing, but too many layers of clothing might be uncomfortable and fire needs to be checked constantly. What can we do ? A warm cover that is also compact and easy to store would be the answer. The answer is blanket. Its main purpose is to keep us warm. It can be made from wool or modern fabrics such as fleece. It is only up to us what we choose. The blankets also differ in size and design, which plays the smallest role in the functionality.
