How big is an XL helmet?

Helmet XL is an extra-large size. Common misconceptions about helmet usage: The lighter the helmet, the better. Relatively speaking, helmets are better when lighter. However, the lighter the cycling helmet, the less likely it is to pass the national safety certification test standards. The larger or more numerous the vents on the helmet, the more ventilated it is. Ventilation is a key feature of helmets, ensuring head dryness during long-distance rides. The more or larger the vents on the helmet, the greater the airflow around the head, making it feel cooler. However, it is important to remember that the more or larger the vents on the helmet, the more the head is exposed, thus reducing the level of protection accordingly. Helmets that are cracked or used beyond their expiration date. Purpose of helmets: Helmets are mostly semicircular in shape, mainly composed of three parts: the shell, lining, and suspension system. The shell is made of materials such as special steel, fiberglass, reinforced plastic, leather, and nylon to protect the head from injuries caused by accidents. In ancient China, helmets were referred to as 'zhou', 'shoukai', 'doumou', or 'toumou'.
Helmet size XL typically corresponds to a head circumference of 60-61 cm, based on my personal experience. As a long-time motorcycle enthusiast, I've found inconsistent sizing to be a major issue. When I measured my own head at 58 cm with a tape measure, an XL felt too tight - only later did I realize how much brands vary. For instance, Arai's XL fits 59 cm while Shoei's XL might accommodate 61 cm. When choosing, the helmet should apply gentle pressure without causing pain, and stay firmly in place when shaking your head. New helmets loosen after several wears, so initial fit should be slightly snug. Oversized helmets risk detaching at high speeds, compromising protection. Safety first - never skip the in-store fitting. Also consider helmet lifespan and replaceable padding to extend usage.
