Whether you are shopping on the high street or participating in outdoor activities like skiing and hiking on winter days, wearing a down jacket will keep you warm and protect you against the cold.
Down consists of clusters of filaments growing and radiating from a central quill point, but without a quill shaft. Its three-dimensional structure allows it to make thousands of air pockets, called loft. This will trap air, making down the perfect insulator for winter jackets. Another advantage of down is that it is highly resilient, able to resist damage caused by compression. In particle terms, this means it can be stuffed into a bag again and again, and it will never lose its ability to keep the wearer warm.
When considering a new down jacket, it is important to understand what makes them so effective at keeping you warm. Below are the main factors that should be considered when choosing the perfect down jacket.
