A shell jacket is a type of outerwear designed to protect the wearer from wind and rain, while also being lightweight and breathable.
It is typically made of synthetic materials such as nylon or polyester, which are coated or laminated with a waterproof and breathable membrane.
This membrane is often made of a material like Gore-Tex or eVent, which allows moisture to escape from the inside of the jacket while preventing water from entering from the outside.
Shell jackets come in a range of styles and features, but they generally have a minimalist design with few pockets or extra features to keep them lightweight and packable.
They are often used as a protective outer layer for outdoor activities such as hiking, skiing, or camping, and can be worn over insulating layers to provide additional warmth and protection from the elements.
