A half helmet, also known as a half-shell helmet, is a type of motorcycle helmet that covers the top, back, and sides of the head but leaves the face exposed. It is popular among riders who prefer a minimalist design and greater airflow. While it offers some protection, it does not provide the full coverage of a full-face helmet, making it less safe in certain situations. Half helmets are often favored for their lightweight feel and comfort during warm weather rides. They come in various styles and colors, allowing riders to express their individuality. However, it's important to note that wearing a half helmet may not meet safety standards in all regions, so riders should check local laws and regulations regarding helmet use.
