A "removable neck" refers to a design feature in certain products, such as clothing or accessories, that allows the neck portion to be detached and reattached. This functionality can enhance versatility, enabling users to customize their look or adjust for comfort. In the context of fashion, a removable neck can be found in items like jackets or sweaters, where the neck section can be swapped for different styles or colors. This feature is also useful for cleaning, as it allows for easier maintenance of the garment.
