Collapsible canopies are a type of umbrella that can be folded up and stored away when not in use. They are often used to provide shade or shelter from the elements, such as rain or sun. They are typically made from lightweight materials, such as nylon or polyester, and come in a variety of sizes and colors. They are also often used for outdoor events, such as weddings or picnics, as they can be easily transported and set up.
