Which helmet type is most commonly used for casual riding?

The three-quarter helmet is commonly used for casual riding because it offers a balance between protection and comfort. This type of helmet covers the top, back, and sides of the head while leaving the face open, allowing for better visibility and airflow. Riders often prefer this design for its lightweight feel and ease of use during leisurely rides.

Additionally, while the three-quarter helmet provides some amount of facial protection compared to a half helmet or half-shell helmet, it also maintains a relaxed riding experience, making it popular for short trips or casual outings.

Other helmet styles, such as full face helmets, provide maximum protection but can be heavier and more restrictive, which might not be as desirable for casual riding situations. Conversely, half helmets and half-shell helmets offer minimal coverage and protection, making them popular among riders who prefer a more open feel, but they do not provide the same level of safety as three-quarter helmets.
