Bivouac shelters

A bivouac shelter, often called a bivvy or bivvy bag, is a lightweight, compact protective cover used by hikers, climbers, and outdoor enthusiasts. It provides basic protection from the elements like wind, rain, and cold when sleeping outdoors, without the bulk of a traditional tent. Typically made from waterproof and breathable materials, bivouacs can be a simple sleeping bag with a protective outer layer or a small tent-like structure. They are ideal for emergency situations or minimalist camping, offering essential shelter while maintaining mobility and reducing pack weight.
